Only 0 should be written to this bit.
Output data for a pin is stored when the pin is
specified as a general purpose I/O port.
9.8.3 Port F Register (PORTF)
PORTF is an 8-bit read-only register that shows port F pin states.
PORTF cannot be modified.

If a port F read is performed while PFDDR bits are
set to 1, the PFDR values are read. If a port F read
is performed while PFDDR bits are cleared to 0, the
pin states are read.
