• PORTF(PF0 − PF2)

PORTF is a 3-bit input-output PORT. The input or the output is selected for each bit by the mask option.

When the port is set as the output, the signal is output through the output terminal by writing data to the

PORTF register(PHY22). When the port is set as the input, the external signal is gotten directly through

the input terminal by reading data from PHY22.
