ROM CORRECTION FUNCTION
This can correct program data in ROM. Up to 2 addresses (2 blocks)
can be corrected, a program for correction is stored in the ROM cor-
rection memory in RAM. The ROM memory for correction is 32 bytes
! 2 blocks.
Block 1 : addresses 030016 to 031F16
Block 2 : addresses 032016 to 033F16
Set an 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 address, the main pro-
gram branches to the correction program stored in the ROM memory
for correction. To return from the correction program to the main pro-
gram, the op code and operand of the JMP instruction (total of 3
bytes) are necessary at the end of the correction program. When the
blocks 1 and 2 are used in series, the above instruction is not needed
at the end of the block 1.
The ROM correction function is controlled by the ROM correction
enable register.
Notes 1 : Specify the 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 main program to the correction program.
3 : Do not set the same ROM correction address to blocks
1 and 2.
