Pin Selection Method and Pin Functions
P2 /PO3/TIOCD3/ This pin is used as the 8-bit timer external clock input pin when external clock
3
TMCI0 is selected with bits CKS2 to CKS0 in TCR0.
The pin function is switched as shown below according to the combination of
the TPU channel 3 setting by bits MD3 to MD0 in TMDR3, bits IOD3 to IOD0 in
TIOR3L, bits CCLR2 to CCLR0 in TCR3, bit NDER3 in NDERL, and bit
P23DDR.
