(3) Bus Cycle Time/Instruction Cycle Time

The LC865520B/16B/12B/08B/04B are constructed to read ROM twice within one instruction cycle.

It has 1.7 times the performance capability for the same instruction cycle compared to our 4-bit
microcontrollers (LC66000 series).
Bus cycle time indicates the speed to read ROM.

- An internal 8-bit baud-rate generator is common to both serial-interface circuits.

(7) Timer

- Timer 0

16-bit timer/counter
2-bit prescaler + 8-bit programmable prescaler

Mode 0 : Two 8-bit timers with programmable prescaler
Mode 1 : 8-bit timer with programmable prescaler + 8-bit counter
Mode 2 : 16-bit timer with programmable prescaler
Mode 3 : 16-bit counter

The resolution of Timer is t

CYC. (

CYC: cycle time)

- Timer 1

16-bit timer/PWM

Mode 0 : Two 8-bit timers
Mode 1 : 8-bit timer + 8-bit PWM
Mode 2 : 16-bit timer
Mode 3 : Variable-bit PWM (9-16bits)

In Mode 0 and Mode 1, the resolution of Timer and PWM is t

CYC.

In Mode 2 and Mode 3, the resolution of Timer and PWM is selectable by program: t

CYC or 1/2

CYC.

- Base timer

Generates an overflow every 500ms for a clock application (using 32.768kHz crystal oscillation for the base timer
oscillator).
Generates an overflow every 976

s, 3.9ms, 15.6ms or 62.5ms (using 32.768kHz crystal oscillation for the base timer

clock)
Clock for the base timer is selectable from 32.768kHz crystal oscillation, system clock, or programmable prescaler
output of Timer 0.

(8) Buzzer output

- Built-in 4KHz and 2KHz buzzer generation function (using 32.768kHz crystal oscillation for the base timer oscillator)

(9) Remote receiver circuit (share with P73/INT3/T0IN terminal)

- Noise Rejection function (The filtering time of the noise rejection filter (1tCYC/16tCYC/64tCYC) can be switched by
program.) (t

CYC: instruction-cycle-time

)

- Polarity switch function

(10) Watchdog timer

- External RC circuit is required.
- Interrupt or system reset is activated when the timer overflows.

(11) Interrupt

- 13-source and 10-vectored interrupt function:

1. External interrupt INT0 (including watchdog timer)
2. External interrupt INT1
3. External interrupt INT2, Timer/counter T0L (lower 8 bits of Timer 0)
4. External interrupt INT3, Base timer
5. Timer/counter T0H (upper 8 bits of Timer 0)
6. Timer T1L (lower 8 bits of Timer 1), Timer T1H (upper 8 bits of Timer 1)
7. Serial interface SIO0
8. Serial interface SIO1
9. AD converter

10. Port 0

- Built-in Interrupt Priority control register

Three interrupt priorities are supported (low, high and highest) and multi-level nesting is possible. Low or high
priority level can be assigned to the 11 interrupt sources of interrupts 3 to 10 shown above by the interrupt priority
control register. For the external interrupt INT0 and INT1(interrupt 1 and 2), low or highest can be set regardless of
the interrupt priority register.

(12) Sub-routine stack levels

- A maximum of 128 levels (set stack inside RAM)

(13) Multiplication and division

16 bits

8-bit (7 instruction-cycle-times)

16 bits / 8-bit (7 instruction-cycle-times)

(14) 3 types of oscillation circuits

- Built-in RC oscillation circuit used for the system clock.
- CF oscillation circuit used for the system clock.
- Crystal oscillation circuit used for the system clock and the time-base clock.

(15) Standby function

- HALT mode

The HALT mode stops the program execution, which minimizes power consumption. This operation mode can be
released by a system reset or an interrupt request.

- HOLD mode

The HOLD mode stops all oscillation circuits: CF, RC and Crystal oscillations. This mode can be released by the
following conditions.

· Feed "L" level to the reset terminal ( RES )
· Feed the selected level to P70/INT0, P71/INT1 terminals
· Feed "L" level to the Port 0
