This pin supplies a voltage of 5 V

10 % while the device is

operating. The rise time (0 to 4.5 V) of V

must not exceed 500

ms. If the rise time is significantly long or if the voltage falls below

the operating voltage but is between 0 V and 3.5 V, the state of an

initial setting diode switch may be read incorrectly.

Input pin of the local oscillator output (VCO) in the AM (MW, LW)

band

When tuned to broadcasts in the MW or LW band, this pin becomes

active. Otherwise, the pin is internally pulled down.

To protect the built-in AC amplifier, block the flow of direct current

with a capacitor, then input the frequency.

Input pin of the local oscillator output (VCO) in the FM band

When tuned to broadcasts in the FM band, this pin becomes active.

Otherwise, the pin is internally pulled down.

Either or DX mode is selected according to a key entry (no auto local function avail-

able).

Each time the MONO/LOC key is pressed, switching occurs between local and DX

modes.

The local output is high in the local mode during auto-tuning (seek, scan, or auto-store).

The auto local function is performed (if available).

The MONO/LOC key becomes ineffective.

Keeping the SEEK UP , SCAN UP , SCAN DWN or P.SCAN key for at least 2

seconds triggers auto-tuning, turns on the "LOC" display, and makes the local output

high. After one cycle of auto-tuning is completed, a search begins in DX mode (with the

"LOC" display off and local output at a low level).

In modes other than auto-tuning , the "LOC" display is off and the local output is low. If

a key for the same operation (for example, the SEEK UP key during seek operation) is

pressed in local mode during auto-tuning, a search begins in DX mode at the same

frequency used when auto-tuning began. If the key is pressed in DX mode, auto-tuning

stops, and the frequency that was selected when auto-tuning began is reselected.

The same operation as above occurs when the AUTO500 is set to 1 (by keeping the

MAN UP or MAN DWN key pressed for at least 0.5 seconds).

MAN UP

MAN DWN

The MAN UP and MAN DWN keys are used to increment and decrement the reception frequency in

radio mode, respectively. During clock display, they are also used in connection with the DISP key to

adjust the clock. They are again used to increase/decrease the volume of sound during electronic volume

control if VKYSEL = 1.

(1) In radio, radio-monitor tape, and radio-monitor CD modes

Either of the following operations occurs depending on the state of the AUTO500 initial setting diode.

(1: Shorted by the diode; 0: Open)

(2) While "

" is displayed in CD mode

The MAN UP and MAN DWN keys are ineffective.

(3) During clock display

While the DISP key is held pressed during clock display, pressing the MAN UP and MAN DWN

keys enables adjusting the minute and hour displays, respectively. See the description of the DISP

key for how to adjust the minute and hour displays.

(4) When the electronic volume control function is effective and VKYSEL = 1:

The MAN UP and MAN DWN keys are used to adjust (increase and decrease) the volume of sound

in the electronic volume control mode selected using the VOL SEL key.

Once an electronic volume control mode is selected using the VOL SEL key, the MAN UP and

MAN DWN keys function in the same way as the VOL UP and VOL DWN keys.

In a mode other than an electronic volume control mode, the MAN UP or MAN DWN key does not

function as a volume control.

Pressing the MAN UP key works for each electronic volume control mode as follows:

Each time the MAN UP or MAN DWN key is pressed, the frequency counter is

incremented ( MAN UP key) or decremented ( MAN DWN key) by one step (one

channel space).

Keeping the key pressed for at least 0.5 seconds speeds the increment/decrement to a

rate of one step per 50 ms.

Each time the MAN UP or MAN DWN key is pressed, the frequency counter is

incremented ( MAN UP key) or decremented ( MAN DWN key) by one step (one

channel space).

Keeping the MAN UP key pressed for at least 0.5 seconds triggers a seek operation in

seek-up mode. This seek operation is the same as that triggered by the SEEK UP

key.

The MONO/LOC key controls MONO (monaural)/STEREO mode and local (local/DX) mode.

(1) Monaural mode control

When this key is pressed and held down for two seconds or more, MONO and STEREO modes can be

switched.

The key is effective, when the current mode is radio, radio-monitor CD, or radio-monitor tape mode and

the FM or MW band is selected. (For the MW band, the key is effective if the MWS initial setting diode

= 1 and the tuner has a stereo capability.)

Each time the key is pressed, switching occurs between MONO and STEREO modes.

The following table lists MONO/STEREO mode and the states of the "ST" display and "MONO" display.

(2) Local mode control

The key is effective when the current mode is radio, radio-monitor CD, or radio-monitor tape mode and

when AUTOLOC initial setting diode = 0.

Each time the key is pressed, switching occurs between local and DX modes (only when the key is

released within two seconds).

The following table lists local/DX mode, the state of the "LOC" display, and LOC pin output.

Note A high level is output only during auto-tuning. The LOC pin is always at a low level during a tuning

type other than auto-tuning.

See the description of the LOC in Chapter 1.

The MTL key controls MTL (METAL) mode. It is effective when the current mode is radio or radio-

P.SCAN

The MUTE key controls the electronic volume control mute function. Pressing the MUTE key in a mode
other than mute mode selects mute (silent) mode. In mute mode, the volume value is displayed, and the
display is caused to blink.
The mute function is reset under the following conditions.

When an effective key other than the DISP key is pressed
When the mode is changed
When a station is detected during a seek or scan operation, with the MUTE pressed.
When the MUTE key is pressed during muting

The POWER key is used to control the power-on/off of the radio in momentary key mode. It is effective

when the IGNITION pin is at a high level. Pressing this key inverts the output of the POWER pin.

When the POWER pin output is set to low (the power is turned off), the tape recorder, CD player and radio

are forced to be turned off even when they have been in the power-on state. In this case, they are turned

off with or without clock display, according to whether they were in clock mode or non-clock mode.

The power-on mode varies as follows according to the state of the RDSET, TPSET, and CDSET switches.

This key functions as a preset scan and auto-storage key. The operation triggered by the key varies

depending on the state of the DISAMEMO initial setting diode.

(1) When DISAMEMO = 0 (with the auto-storage function):

The operation varies depending on the timing at which the key is operated.

(a) If the key is released within 2 seconds:

The preset scan operation begins immediately when the key is released.

(b) If the key is pressed for at least 2 seconds:

The auto-storage operation begins when 2 seconds elapse.

(2) When DISAMEMO = 1 (without the auto-storage function):

The preset scan operation begins immediately when the key is pressed.

The preset scan and auto-storage functions are described below.

Preset scan operation

The contents of each preset memory are called for 5 seconds each time automatically.

If a frequency other than those in the preset memories is being received, calling begins at M1. If

a frequency recorded in a preset memory is being received, calling begins at the preset memory

numbered one higher than that preset memory (for example, at the M4 preset memory if a

frequency recorded in the M3 preset memory is being received). This operation is illustrated

below.

The same operation occurs for the MW (MW1 and MW2) and LW bands.

When the next preset memory is accessed after a 5-second hold period, a beep is generated. During each

5-second period, the preset memory number display blinks at 1 Hz (with a duty cycle of 50%). The "CH"

display does not blink.

To stop preset memory scanning during a 5-second hold period, press the P. SCAN key again or a preset

memory key that corresponds to the preset memory being currently accessed. It is possible to write to a

preset memory when another preset memory is on hold (for example, write to the M5 when the M1 is on

hold). When a write operation is completed, the preset scan operation ends.

Hold down one of the M1 to M6 keys for at least 2 seconds during the preset scan operation. The

frequency currently being received is written into the preset memory corresponding to the pressed key.

The preset scan operation ends immediately when any of these keys is pressed.

During the preset scan, each key functions as follows:

P.SCAN

Auto-storage function

Broadcasting stations are searched for automatically. The frequency of a detected station is written

to a preset memory. A method used to detect a station is determined according to the states of the

ENAMIF and ENFMIF initial setting diodes. A broadcasting station search begins at the frequency

being currently received and is performed through the frequencies in the ascending order.

When a station is detected, its frequency is written to a preset memory.

For the voltage with SD, see the description of the SD in Chapter 1.

The auto-storage operation varies depending on the state of the AUTOLOC initial setting diode as

follows:

(1) When AUTOLOC = 0 (with no auto local function):

The auto-storage function varies depending on which mode has been selected, local or DX, when the

function begins.

(a) If DX mode has been selected when the auto-storage function starts:

A search beings at the frequency being currently received and continues in the ascending order of

the frequency. When all frequencies are searched through, the search operation ends. If the

P. SCAN key is pressed during the search operation, the auto-storage operation ends, and the

frequency selected when the auto-storage operation began is received.

When all frequencies are searched through, if at least one station is detected, the contents of the

preset memories are updated, and the preset scan begins at the M1 preset memory.

How the contents of the preset memories are updated varies depending on the number of stations

detected.

If six or more stations are detected:

If six or more stations are detected, six stations with a higher SD input are selected and

written to the preset memories. A lower frequency is written to a lower-numbered preset

memory.

If less than six stations are detected:

If less than six stations are detected, lower frequencies are written to lower-numbered preset

memories. The contents of a preset memory will not be changed if there is no frequency

corresponding to it.

(b) If local mode has been selected when the auto-storage function starts:

A search begins in local mode at the frequency being currently received and continues in the

ascending order of the frequency. When all frequencies are searched through, if six or more

stations are not detected, the search switches to DX mode and continues in it. If six or more

stations are detected in local mode, or all frequencies are searched through in DX mode, the

auto-storage operation ends.

Pressing the P. SCAN key during the search operation stops the auto-storage operation, and

causes the frequency selected when the auto-storage memory began to be received.

If six or more stations are detected in local mode, or all frequencies are searched through in DX

mode, the auto-storage operation ends. If at least one station is detected, the contents of the

preset memories are updated, and the preset scan begins with the M1 preset memory.

How the contents of the preset memories are updated varies depending on the number of stations

detected, as follows:

If six or more stations are detected in local mode:

If six or more stations are detected, six stations with a higher SD input are selected and

written to the preset memories. A lower frequency is written to a lower-numbered preset

memory

If less than six stations are detected in local mode and some are detected in DX mode,

resulting in a total of six or more stations being detected:

Stations detected in DX mode with higher SD input levels are selected and added to the

number of stations detected in local mode so that the total becomes six. In this case, the

stations detected in local mode are excluded from those detected in DX mode.

The frequencies of the six stations are written to the preset memories, with a lower frequency

written to a lower-numbered preset memory.

Description

P.SCAN

If less than six stations are detected in local mode and some are detected in DX mode,

resulting in a total of less than six stations being detected:

If the same station is detected in DX and local modes, the station detected in DX mode is

deleted so that the same frequency will not be written to two preset memories. The frequen-

cies of the less than six stations detected are written to the preset memories, with a lower

frequency written to a lower-numbered preset memory. The contents of a preset memory will

not be changed if there is no frequency corresponding to it.

(2) When AUTOLOC = 1 (with the local function):

A search begins in local mode at the frequency being currently received and continues in the ascend-

ing order of the frequency. When all frequencies are searched through, if six or more stations are not

detected, the search switches to DX mode and continues in it. If six or more stations are detected in

local mode, or all frequencies are searched through in DX mode, the auto-storage operations ends.

Pressing the P. SCAN key in local mode switches to DX mode, and restarts the search operation at

the frequency selected when the previous search began. Any stations detected in local mode are

made ineffective. (Stations detected in local mode are excluded during preset memory updating.)

Pressing the P. SCAN key in DX mode ends the auto-storage operation, and causes the frequency

selected when the auto-storage operation began to be received.

If six or more stations are detected in local mode, or all frequencies are searched through in DX mode,

the auto-storage operation ends. If at least one station is detected, the contents of the preset memo-

ries are updated, and the preset scan begins with the M1 preset memory.

How the contents of the preset memories are updated varies depending on the number of stations

detected, as follows:

If six or more stations are detected in local mode:

If six or more stations are detected in local mode, six stations with a higher SD input are selected

and written to the preset memories, with a lower frequency written to a lower-numbered preset

memory.

If less than six stations are detected in local mode, and some are detected in DX mode,

resulting in a total of six or more stations being detected:

Stations detected in DX mode with higher SD input levels are selected and added to the number of

stations detected in local mode so that the total becomes six. In this case, the stations detected in

local mode are excluded from those detected in DX mode.

The frequencies of the six stations are written to the preset memories, with a lower frequency

written to a lower-numbered preset memory.

If less than six stations are detected in local mode and some are detected in DX mode,

resulting in a total of less than six stations being detected:

If the same station is detected in DX and local modes, the station detected in DX mode is deleted

so that the same frequency will not be written to two preset memories. The frequencies of the less

than six stations detected are written to the preset memories, with a lower frequency written to a

lower-numbered preset memory. The contents of a preset memory will not be changed if there is

no frequency corresponding to it.

Note When using alarm mode, always pull up the CE pin.

The SCAN UP and SCAN DWN keys are used for auto-tuning (scan operation).

Pressing the SCAN UP key ( SCAN DWN key) increases (decreases) the frequency by one channel

space and checks whether there is a broadcasting station at each reception frequency (frequency counter

and SD signal). If a broadcasting station is detected, the corresponding frequency is held for five seconds.

If no key is pressed within this hold time of five seconds, the seek operation restarts. If another broadcast-

ing station is detected, the corresponding frequency is held in the frequency counter for five seconds. This

operation is repeated (scan operation) sequentially.

The frequency display blinks at 1 Hz (with a duty cycle of 50%) during the five-second hold time. A beep

occurs at the end of the hold time.

SEEK UP

The SEEK UP key is used for auto-tuning (seek operation).

Pressing the SEEK UP key increases the frequency by one channel space and checks whether there is a

broadcasting station at each reception frequency (by a method determined depending on the states of the

ENAMIF and ENFMIF initial setting diodes). If a broadcasting station is detected, the seek operation ends.

The seek operation performed varies with the state of the AUTOLOC initial setting diode as follows:

(1) When AUTOLOC = 0 (with no auto local function):

A search operation begins at the frequency currently being received.

The search operation continues in local or DX mode whichever has been selected when the search

operation starts, until a station is detected.

(2) When AUTOLOC = 1 (with an auto local function):

A search operation begins at the frequency being currently received in local mode. When all frequen-

cies are searched through in local mode, a search operation is switched to DX mode and continues

until a station is detected. If the SEEK UP key is pressed in local mode, DX mode is selected, and a

search operation restarts with the same frequency as for the previous search. If the SEEK UP key is

pressed during a search in DX mode, the search operation ends, and the frequency at which the

search operation began is selected.

When using the SEEK UP key, set the AUTO500 initial setting diode to 0. Setting it to 1 disables the

SEEK UP key.

The SEEK UP key functions during the search operation as follows:

(2) When AUTO500 = 1:

If the MAN UP key is pressed in seek-up mode, the seek operation stops,

and the frequency that was selected when the seek operation began is

reselected. If the auto local function is being used, local mode is switched.

The seek operation stops, and the operation corresponding to the pressed key

begins at the frequency that was selected when the key was pressed.

In radio, radio-monitor tape, and radio-monitor CD modes, the seek operation

VOL UP

The VOL UP key is used to adjust the volume of sound in each electronic volume control mode. The

operation depends on the state of the VKYSEL initial setting diode.

(1: Shorted by the diode; 0: Open)

VKYSEL

Description

Pressing the VOL UP key in a mode other than an electronic volume control mode

selects volume mode and increases the volume of sound.

In an electronic volume control mode selected by the VOL SEL key, pressing the

VOL UP key activates the operation corresponding to the selected mode as follows:

Keeping the VOL UP key pressed for at least 0.5 seconds controls the volume continu-

ously.

If no key is pressed for at least 3 seconds, the mode previous to the current electronic

volume control mode is reselected.

The VOL UP key is ineffective. After an electronic volume control mode is selected

using the VOL SEL key, the MAN UP key can be used to perform the same adjust-

ment that would be performed using the VOL UP key.

Pressing the MAN UP key in a mode other than an electronic volume control mode

does not select volume mode. See the descriptions of the MAN UP and MAN DWN

keys for details.

APPENDIX COMMUNICATION WITH ELECTRONIC VOLUME CONTROL IC (I

C BUS INTERFACE)

The

PD17012-058 sends specified data, such as volume and balance data, to the electronic volume control IC.

Two buses, the data bus and clock bus, are necessary to output data to the electronic volume control IC. Data and

clock signals are output from the EVOL_DA pin (pin 2) and EVOL_SCK pin (pin 1) of the

PD17012-058.

Figure A-1. Pin Connections (Electronic Volume Control)

Electronic volume control data consists of nine bits (eight bits for data and a check bit). The electronic volume

address (nine bits) and control data (nine bits) are sequentially transferred N times, where N is the number of

transferred data items, such as the volume and balance data.

NOTES FOR CMOS DEVICES

PRECAUTION AGAINST ESD FOR SEMICONDUCTORS

Note: Strong electric field, when exposed to a MOS device, can cause destruction

of the gate oxide and ultimately degrade the device operation. Steps must

be taken to stop generation of static electricity as much as possible, and

quickly dissipate it once, when it has occurred. Environmental control must

be adequate. When it is dry, humidifier should be used. It is recommended

to avoid using insulators that easily build static electricity. Semiconductor

devices must be stored and transported in an anti-static container, static

shielding bag or conductive material. All test and measurement tools

including work bench and floor should be grounded. The operator should

be grounded using wrist strap. Semiconductor devices must not be touched

with bare hands. Similar precautions need to be taken for PW boards with

semiconductor devices on it.

HANDLING OF UNUSED INPUT PINS FOR CMOS

Note: No connection for CMOS device inputs can be cause of malfunction. If no

connection is provided to the input pins, it is possible that an internal input

level may be generated due to noise, etc., hence causing malfunction. CMOS

device behave differently than Bipolar or NMOS devices. Input levels of

CMOS devices must be fixed high or low by using a pull-up or pull-down

circuitry. Each unused pin should be connected to V

or GND with a

resistor, if it is considered to have a possibility of being an output pin. All

handling related to the unused pins must be judged device by device and

related specifications governing the devices.

STATUS BEFORE INITIALIZATION OF MOS DEVICES

Note: Power-on does not necessarily define initial status of MOS device. Produc-

tion process of MOS does not define the initial operation status of the device.

Immediately after the power source is turned ON, the devices with reset

function have not yet been initialized. Hence, power-on does not guarantee

out-pin levels, I/O settings or contents of registers. Device is not initialized

until the reset signal is received. Reset operation must be executed imme-

diately after power-on for devices having reset function.
