48 / 138 page  M37151M6/M8/MA/MC/MF-XXXFP, M37151EFFP Rev.1.00 Nov 01, 2002 page 48 of 136 REJ03B0129-0100Z Fig. 8.9.1 ROM Correction Address Registers 8.9 ROM CORRECTION FUNCTION This can correct program data in the ROM. Up to 2 addresses can be corrected; a program for correction is stored in the ROM correction vector in the RAM as the top address. There are 2 vectors for ROM correction:. Vector 1 : address 030016 Vector 2 : address 032016 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 top address of the ROM correction vector, the main program branches to the correction program stored in the ROM memory. 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 both vectors 1 and 2. 020A16 ROM correction address 1 (high-order) 020B16 ROM correction address 1 (low-order) 020C16 ROM correction address 2 (high-order) 020D16 ROM correction address 2 (low-order) b7 b6 b5 b4 b3 b2 b1 b0 ROM correction enable register (RCR) [Address 020E 16] B After reset RW ROM Correction Enable Register 0 Vector 1 enable bit (RC0) Name Functions 0: Disabled 1: Enabled 1 Vector 2 enable bit (RC1) 0: Disabled 1: Enabled 2 to 7 Nothing is assigned. These bits are write disable bits. When these bits are read out, the values are “0.” 0 0 0 RW RW R— |
