Pin Functions
Modes 4 to 6: In modes 4 to 6, the corresponding port B pins become address outputs in
accordance with the setting of bits AE3 to AE0 in PFCR. When pins are not used as address
outputs, they function as TPU I/O pins and I/O ports.
Port B pin functions in modes 4 to 6 are shown in figure 9-9.
Figure 9-9 Port B Pin Functions (Modes 4 to 6)
Mode 7: In mode 7, port B pins function as I/O ports and TPU I/O pins (TIOCA3, TIOCB3,
TIOCC3, TIOCD3, TIOCA4, TIOCB4, TIOCA5, and TIOCB5). Input or output can be specified
for each pin on an individual bit basis. Setting a PBDDR bit to 1 makes the corresponding port B
pin an output port, while clearing the bit to 0 makes the pin an input port.
Port B pin functions in mode 7 are shown in figure 9-10.
