Pin Functions and Selection Method
P17/IRQ3/TMIF
The pin function depends on bit IRQ3 in PMR1, bits CKSL2 to CKSL0 in TCRF,
and bit PCR17 in PCR1.

P16/IRQ2/TMIC
Note: When using as TMIF input pin, clear bit IEN3 in IENR1 to 0, disabling
IRQ3 interrupts.
The pin function depends on bit IRQ2 in PMR1, bits TMC2 to TMC0 in TMC, and
bit PCR16 in PCR1.
