Section 9 I/O Ports
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 9.9.
