Pin Functions and Selection Method
The pin function depends on bit IRQ3 in PMR1, bits CKSL2 to CKSL0 in TCRF,
and bit PCR1₇ in PCR1.

IRQ₃/TMIF
input pin
Note: When this pin is used as the TMIF input pin, clear bit IEN3 to 0 in IENR1
to disable the IRQ₃ interrupt.
The pin function depends on bits IRQ2 in PMR1 and bit PCR1₆ in PCR1.
