Section 7 I/O Ports
7.8 Port F
Port F is an 8-bit I/O port that also has other functions. Port F has the following registers.
• Port F data direction register (PFDDR)
• Port F data register (PFDR)
• Port F register (PORTF)
7.8.1 Port F Data Direction Register (PFDDR)
The individual bits of PFDDR specify input or output for the pins of port F.

When the pin function is specified to a general I/O port,
setting this bit to 1 makes the PF7 pin the φ output pin,
while clearing this bit to 0 makes the pin an input pin.

When a pin function is specified to a general I/O port,
W
setting this bit to 1 makes the corresponding port F pin
an output pin, while clearing this bit to 0 makes the pin
W
an input pin.
