How to use
(1) Specification of option
(2) How to program for the EPROM
(3) How to use the data security function
The LC86P7148 must be programmed after specifying option data.
specified option file and the file created by our macro assembler “M86K.EXE” are linked by our linkage loader
“L86K.EXE” which creates .HEX file, then the option code is put in the option specified area (0FF00H to 0FFFFH) of
its .HEX file.
The LC86P7148 can be programmed by EPROM programmer with attachment ; W86EP7148Q
• Recommended EPROM programmer
• “27512 (Vpp=12.5V) Intel high speed programming” mode available.
“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.
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
