8.9 ROM CORRECTION FUNCTION

This can correct program data in ROM. Up to 3 addresses can be

corrected, a program for correction is stored in the ROM correction

vector in RAM as the top address. The ROM correction vectors are 3

vectors.

Vector 1 : address 02C016

Vector 2 : address 02E016

Vector 3 : address 030016

Set the address of the ROM data to be corrected into the ROM cor-

rection address register. When the value of the counter matches the

ROM data address in the ROM correction vector as the top address,

the main program branches to the correction program stored in the

ROM memory for correction. To return from the correction program

to the main program, the op code and operand of the JMP instruction

(total of 3 bytes) are necessary at the end of the correction program.

The ROM correction function is controlled by the ROM correction

enable register.

Notes 1: Specify t he first address (op code address) of each

instruction as the ROM correction address.

2: Use the JMP instruction (total of 3 bytes) to return from

the correction program to the main program.

3: Do not set the same ROM correction address to vectors 1 to 3.
