8.1.15 Port
F
Port F is a 7-bit I/O port. Port F pins can also function as the PWMX output and EtherC control
input/output pins. Port F has the following registers.
•
Port F data direction register (PFDDR)
•
Port F output data register (PFODR)
•
Port F input data register (PFPIN)
(1)
Port F Data Direction Register (PFDDR)
The individual bits of PFDDR specify input or output for the port F pins. PFDDR is initialized
only by a system reset, and retains the value even if an internal reset signal of the WDT is
generated.

When set to 1, the corresponding pin functions as an
output port pin; when cleared to 0, functions as an
input port pin.
Since this register is allocated to the same address as
PFPIN, states of the port F pins are returned when
this register is read.
