(6) Flash address pointer H compare register and flash address pointer L compare register (FLAPHC and
FLAPLC)
These registers are used to specify the address range in which the internal sequencer operates when the flash
memory is verified in the self-programming mode.
Set FLAPHC to the same value as that of FLAPH. Set the last address of the range in which verification is to
be executed to FLAPLC.
These registers are set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
Caution Be sure to clear bits 4 to 7 of flash address pointer H (FLAPH) and flash address pointer H
