(4) External interrupt mode register 1 (INTM1)
INTM1 is used to specify an effective edge for INTP3 and INTLVI0.
INTM1 is manipulated using an 8-bit memory manipulation instruction.
A RESET input clears INTM1 to 00H.

Cautions 1. Bits 4 to 7 must be fixed to 0.
2. Before setting INTM1, set the corresponding interrupt mask flag register to 1 to disable
interrupts.
To enable interrupts, clear (0) the corresponding interrupt request flag, then the
corresponding interrupt mask flag register.
