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.

Pin function
P17 input pin P17 output pin IRQ3 input pin 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 bit PCR16 in PCR1.

Note: Pin 16 and the associated function are not implemented on the H8/38124
Group.
The pin function depends on bit IRQ4 in PMR1, bit TRGE in AMR, and bit PCR14
in PCR1.
