(3) External interrupt mode register 0 (INTM0)
This register is used to specify the valid edge for INTP0.
INTM0 is set using an 8-bit memory manipulation instruction.
RESET input sets this register to 00H.

Both rising and falling edges
Cautions 1. Always set bits 0, 1, and 4 to 7 to 0.
2. Before setting INTM0, set (1) the interrupt mask flag (PMK0) to disable interrupts.
To enable interrupts, clear (0) the interrupt request flag (PIF0), then clear (0) the interrupt
mask flag (PMK0).
