20.2 Control Registers
(1) Correction address registers 0 to 3 (CORAD0 to CORAD3)
Note Be sure to clear these bits to 0.
The CORAD0 to CORAD3 registers set the first address of the correction program.
The program can be corrected at up to four places because four CORADn registers are provided (n = 0 to 3).
The CORADn register can be read or written in 32-bit units.
If the higher 16 bits of the CORADn register are used as the CORADnH register, and the lower 16 bits as the
CORADnL register, these registers can be read or written in 16-bit units.
Reset sets these registers to 00000000H.
Because the ROM capacity differs depending on the product, set correction addresses in the following ranges.
Fix bits 0 and 20 to 31 to “0”.
