7.3.1 Port A Data Register
Technical Data
74
Address:
Port A is an 8-bit, general-purpose, bidirectional input/output (I/O) port.
The port A data register (PORTA) shown in
latch for each of the eight port A pins. When a port A pin is programmed
to be an output, the state of its data register bit determines the state of
the output pin. When a port A pin is programmed to be an input, reading
the port A data register returns the logic state of the pin.

Read:
Write:
These read/write bits are software programmable. Data direction of
each bit is under the control of the corresponding bit in data direction
register A. Reset has no effect on port A data.
