Mode 7 (On-Chip ROM Version Only): In mode 7, port B pins function as I/O ports. 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 9-12.
Mode 6 (On-Chip ROM Version Only): In mode 6, port B pins function as address outputs or input ports. Input or
output can be specified on an individual bit basis. Setting a PBDDR bit to 1 makes the corresponding port B pin an
address output, while clearing the bit to 0 makes the pin an input port.
Port B pin functions in mode 6 are shown in figure 9-13.
