Mode 6 (On-Chip ROM Version Only): In mode 6, port A pins function as address outputs or input ports and interrupt
input pins. Input or output can be specified on an individual bit basis. Setting a PADDR bit to 1 makes the corresponding
port A pin an address output, while clearing the bit to 0 makes the pin an input port.
Port A pin functions in mode 6 are shown in figure 9-9.
Modes 4 and 5: In modes 4 and 5, the lower 5 bits of port A are designated as address outputs automatically, while the
upper 3 bits function as address outputs or input ports and interrupt input pins. Input or output can be specified
individually for the upper 3 bits. Setting one of bits PA7DDR to PA5DDR to 1 makes the corresponding port A pin an
address output, while clearing the bit to 0 makes the pin an input port.
Port A pin functions in modes 4 and 5 are shown in figure 9-10.
