Pin
P10/PO8/TIOCA0/
DACK0/A20
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the operating mode, and the TPU channel 0 setting (by bits MD3 to MD0 in
TMDR0, bits IOA3 to IOA0 in TIOR0H, and bits CCLR2 to CCLR0 in TCR0),
bits AE3 to AE0 in PFCR, bit NDER8 in NDERH, SAE0 bit in DMABCRH, and
bit P10DDR.
