Symbol
These registers set the start address (correction address) of the instruction(s) to be corrected in the flash
memory.
The ROM correction corrects two places (max.) of the program. Addresses are set to two registers, CORAD0
and CORAD1. If only one place needs to be corrected, set the address to either of the registers.
CORAD0 and CORAD1 are set by a 16-bit memory manipulation instruction.
RESET input clears CORAD0 and CORAD1 to 0000H.
Cautions 1. Set the CORAD0 and CORAD1 when bit 1 (COREN0) and bit 3 (COREN1) of the correction
The comparator always compares the correction address value set in correction address registers 0 and 1
(CORAD0, CORAD1) with the fetch address value. When bit 1 (COREN0) or bit 3 (COREN1) of the correction
control register (CORCN) is 1 and the correction address matches the fetch address value, the correction
branch request signal (BR !F7FDH) is generated from the ROM correction circuit.

2. Only addresses where operation codes are stored can be set in CORAD0 and CORAD1.
3. Do not set the following addresses to CORAD0 and CORAD1.
control register (CORCN: see Figure 25-3) are 0.
Address value in table area of table reference instruction (CALLT instruction): 0040H to
007FH
Address value in vector table area: 0000H to 003FH
