10A.8.3 Pin Functions
Port B pins also function as TPU output pins (TIOCA3, TIOCB3, TIOCC3, TIOCD3, TIOCA4,
TIOCB4, TIOCC4, and TIOCD4) and address bus output pins (A15 to A8).
Table 10A.14 Port B Pin Functions
Pin Selection Method and Pin Functions
PB7/A15/TIOCB5 The function of this pin changes according to the operating mode and the
setting of bits AE3 to AE0 in PFCR; the TPU5 settings of bits MD3 to MD0 in
TMDR5, bits IOB3 to IOB0 in TIOR5, and the CCLR1 and CCLR0 bits in TCR5;
and the setting of the PB7DDR bit.
