8.6.3
Modes 1, 2, 3 and 7 * : In mode 1, 2, 3, and 7 * , port A pins function as I/O ports. Input or output
can be specified for each pin on an individual bit basis. Setting a PADDR bit to 1 makes the
corresponding port A pin an output port, while clearing the bit to 0 makes the pin an input port.
Port A pin functions in modes 1, 2, 3, and 7 are shown in figure 8.6.
Modes 4 and 5: In modes 4 and 5, the lower 4 bits of port A are designated as address outputs
automatically.
Port A pin functions in modes 4 and 5 are shown in figure 8.7.
Mode 6 * : In mode 6 * , port A pins function as address outputs or input ports. 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 8.8.
Note: * Modes 1 to 3 are not available on the F-ZTAT version.
Pin Functions
Modes 2, 3, 6, and 7 are not available on the ROMless version.
