Selection Method and Pin Functions
This pin is used as the 8-bit timer external clock input pin when an 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, bits IOB3 to IOB0
in TIOR4, and bits CCLR1 and CCLR0 in TCR4), bit NDER5 in NDERL, and bit
P25DDR.
