(1) External interrupt falling, rising edge specification register 0 (INTF0, INTR0)
Remark
The INTF0 and INTR0 registers are 8-bit registers that specify detection of the falling and rising edges of the
NMI pin via bit 2 and the external interrupt pins (INTP0 to INTP3) via bits 3 to 6.
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
Caution Be sure to clear the INTF0n and INTR0n bits to 00 when these registers are not used for the

Caution When switching from the port function to the external interrupt function (alternate function),

an edge might be detected. Therefore, set the INTF0n and INTR0n bits to 00, and then specify
the external interrupt function (PMC0.PMC0n bit = 1).
When switching from the external interrupt function to the port function, an edge might be
detected as well. Therefore, set the INTF0n and INTR0n bits to 00, and then specify the port
function (PMC0.PMC0n bit = 0).
