/PO5/TIOCB4/
TMCI1
This pin is used as the 8-bit timer external clock input pin when external clock
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.
