Comparator input/port E input option
Whether the 4 port pins PE0/CMP0, PE1/CMP1, PE2/CMP2, and PE3/CMP3 function as comparator inputs or as port
E inputs can be selected.

Comparator function option
One of two options relating to the comparator function can be selected.
Usage Procedures
Option specification procedures
User options can be selected interactively by running the LC6529 option entry software (SU60K). This creates an
option file (file.opt).
Assembling the user program with the macro assembler (M60K) creates an object file. An evaluation file (file.eva) can
be created by linking the object file and the option file with the linker (L60K). Then, a HEX format object file, which
includes both the user program and the mask options, can be created by converting the evaluation file with the file
conversion software (E2H60K). This creates the option codes in the option specification area (locations 400 to 404H).
It is also possible to store data directly to the option specification area. Refer to the option code creation table on page 9
to do this.
Refer to the “LC65/66K Software Manual” for details.
EPROM programming procedure
A general-purpose EPROM programmer can be used to write the created data to the LC65P29 by using a special-
purpose write conversion board (either the W65EP29D or the W65EP29M).
— The EPROM programmers listed below can be used.
— The “27512 (VPP: 12.5 V) Intel fast write” method must be used for writing. Specify locations 0 to 404 as the
address settings, and make sure that the DASEC jumper is in the off position.
Using the data security function
The data security function is a function that prevents data written previously to the microcontroller EPROM from being
read out. Use the following procedure to apply the data security to the LC65P29.
1. Set the DASEC jumper on the write conversion board to the on position.
2. Write the data once again.
At this point, the EPROM writer will indicate an error since this function has operated, but actually, no error has
occurred in either the programmer or the IC.
Notes: The data security function will not be applied if the data value FF is written to all address in step 2.
The data security function will not be applied if the sequence BLANK

PROGRAM
→
VERIFY is performed
at step 2.
Always return the jumper to the off position after performing this procedure.
