To develop code on a PIC16C52 device, a
PIC16C54/JW part can be used. In order to use a
PIC16C54/JW device, the following conditions should
be followed:
1. A PIC16C54/JW has 512 words (0x1FF) of program
memory, whereas a PIC16C52 has 384
bytes (0x17F) of program memory. The “extra”
locations should be programmed as follows:
a) Location 0x180 should be programmed with
a “GOTO 0x00” instruction
b) Locations 0x181 through 0x1FF should be
programmed with a “GOTO 0x17F”
instruction.
See Figure 1 for details, and for a standard
“skeleton” program, use the code in
Example 1.
