Pin Functions and Selection Method

P10/

TIOCA0/

A20

The pin function is switched as shown below according to the combination of the

operating mode, the TPU channel 0 settings (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, and

bit P10DDR.
