Pin
Selection Method and Pin Functions
P12/PO10/
The pin function is switched as shown below according to the combination of
TIOCC0/TCLKA
the operating mode, and the TPU channel 0 setting (by bits MD3 to MD0 in
TMDR0, bits IOC3 to IOC0 in TIOR0L, and bits CCLR2 to CCLR0 in TCR0),
bits TPSC2 to TPSC0 in TCR0 to TCR5, bit NDER10 in NDERH, and bit
P12DDR.
