9.13
Port F is an 8-bit I/O port and has the following registers.
• Port F data direction register (PFDDR)
• Port F data register (PFDR)
• Port F register (PORTF)
9.13.1
PFDDR specifies input or output the port F pins using the individual bits. PFDDR cannot be read;
if it is, the read value is undefined. Since this register is a write-only register, bit-manipulation
instructions should not be used when writing. See section 2.9.4, Access Method for Registers with
Write-only Bits.

Description
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port F pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
