Serial writer load program area
This kilobyte of ROM, starting at address x'0x80000', holds the load program
for the serial writer. This area is write-protected in the hardware. Panasonic
provides the load program.
Fixed user program area
These 7 kilobytes of ROM starting at address x'0x80400', hold the fixed user
program. This area is write-protected in the hardware. (You can program this area
with a parallel writer.)
Security code
This byte holds the password for the serial writer. Enter an 8-character ASCII
code in this space.
Reserved area
Do not write to this area.
Branch instruction to reset service routine
Normally, reset servicing starts at address x'0x80000', but the soft branch
instruction in the serial writer load program branches to x'0x82010'. This
address must hold a JMP instruction pointing to the real start address for the reset
service routine.
