20.3 Register Controlling Key Interrupt

(1) Key return mode register (KRM)
Cautions 1. If any of the KRM0 to KRM6 bits used is set to 1, set bits 0 to 6 (PU70 to PU76) of the
This register controls the KRM0 to KRM6 bits using the KR0 to KR6 signals, respectively.
KRM is set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets KRM to 00H.
2. If KRM is changed, the interrupt request flag may be set. Therefore, disable interrupts and
3. The bits not used in the key interrupt mode can be used as normal ports.

then change the KRM register. Clear the interrupt request flag and enable interrupts.
