Pin Selection Method and Pin Functions
P2 /PO5/TIOCB4/ This pin is used as the 8-bit timer external clock input pin when external clock
5
TMCI1 is selected with bits CKS2 to CKS0 in TCR1.
The pin function is switched as shown below according to the combination of
the TPU channel 4 setting by bits MD3 to MD0 in TMDR4 and bits IOB3 to
IOB0 in TIOR4, bits CCLR1 and CCLR0 in TCR4, bit NDER5 in NDERL, and
bit P25DDR.
