I/O PORTS

The I/O ports have direction registers which determine the input/

output direction of each individual pin. Each bit in a direction reg-

ister corresponds to one pin, and each pin can be set to be input

port or output port.

When “0” is written to the bit corresponding to a pin, that pin be-

comes an input pin. When “1” is written to that bit, that pin

becomes an output pin.

If data is read from a pin which is set to output, the value of the

port output latch is read, not the value of the pin itself. Pins set to

input are floating. If a pin set to input is written to, only the port

output latch is written to and the pin remains floating.
