10.11.2 Port F Data Register (PFDR)
PFDR stores output data for port F pins.
PFDR stores output data for port F pins.
Bit Bit Name Initial Value R/W Description
7 PF7DR 0 R/W
6 PF6DR 0 R/W
5 PF5DR 0 R/W
4 PF4DR 0 R/W
3 PF3DR 0 R/W
2 PF2DR 0 R/W
1 PF1DR 0 R/W
Output data for a pin is stored when the pin is
specified as a general purpose output port.

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.
