Pin Selection Method and Pin Functions
PB0/A8/TIOCA3
The function of this pin changes according to the operating mode and the
setting of bits AE3 to AE0 in PFCR; the TPU3 settings of bits MD3 to MD0 in
TMDR3, bits IOA3 to IOA0 in TIORH3, and bits CCLR2 to CCLR0 in TCR3;
and the setting of the PB0DDR bit.
