Pin Functions
Port 1 Pin Functions
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 bits IRQ2 in PMR1 and bit PCR1
The pin function depends on bit IRQ1 in PMR1, bits TMC2 to TMC0 in TMC, and
bit PCR1
Note: When this pin is used as the TMIC input pin, clear bit IEN1 to 0 in IENR1
The pin function depends on bit IRQ4 in PMR1, bit TRGE in AMR, and bit PCR1
in PCR1.
Note: When this pin is used as the ADTRG input pin, clear bit IEN4 to 0 in
CKSL2 to CKSL0
TMC2 to TMC0
