Pin
PB1/A9/TIOCB3
Selection Method and Pin Functions
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 IOB3 to IOB0 in TIORH3, and bits CCLR2 to CCLR0 in TCR3;
and the setting of the PB1DDR bit.
