Pin Functions and Selection Method
The pin function depends on bit IRQ3 in PMR1, bits CKSL2 to CKSL0 in TCRF,
and bit PCR1
Note: When this pin is used as the TMIF input pin, clear bit IEN3 to 0 in IENR1
The pin function depends on bit PCR1
Note: Pin 16 and the associated function are not implemented on the H8/38124
