The option is specified until 3ms after
going to a `H' level to the reset
terminal by degrees. The program is
executed from 00H of the program
counter.

(1) Option
The option data is created by the option specified program "SU86K.EXE". The created option data is linked to the
program area by linkage loader "L86K.EXE".
(2) ROM space
LC86E7248 and LC867200 series use 256 bytes that is addressed on 0FF00H to 0FFFFH in the program memory as the
option specified data area. These program memory capacity are 49152 bytes that is addressed on 0000H to 0BFFFH.

How to use
(1) Specification of option
Programming data for PROM of the LC86E7248 is required.
Debugged evaluation file (EVA file) must be converted to an INTEL-HEX formatted file (HEX file) with file converter
program, EVA2HEX.EXE. The HEX file is used as the programming data for the LC86P6548.
(2) How to program for the EPROM
The LC86E7248 can be programmed by EPROM programmer with attachment ; W86EP7248Q

MODEL1890A
"27512 (Vpp=12.5V) Intel high speed programming" mode available. The address must be set to "0 to 0FFFFH" and a
jumper (DASEC) must be set to `OFF' at programming.
(3) How to use the data security function
"Data security" is the disabled function to read the data of the EPROM.
The following is the process in order to execute the data security.
1. Set `ON' the jumper of attachment.
2. Program again. Then EPROM programmer displays the error. The error means normally activity of the data
security. It is not a trouble of the EPROM programmer or the LSI.
Notes
Data security is not executed when the data of all address have `FFH' at the sequence 2 above.
The programming by a sequential operation "BLANK=>PROGRAM=>VERIFY" cannot be executed data security at the
sequence 2 above.
Set to `OFF' the jumper after executing the data security.
(4) How to eliminate
The programming data can be erased by using the EPROM eraser.
(5) Shielding
The UVEPROM (ultraviolet erasable programmable ROM) is in it. Put the seal on the window in use.
