Section 10 I/O Ports
10.11
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)
10.11.1 Port F Data Direction Register (PFDDR)
PFDDR specifies input or output of the port F pins using the individual bits. PFDDR cannot be
read; if it is, an undefined value will be read. This register is a write-only register, and cannot be
written by bit manipulation instruction. For details, see section 2.9.4, Access Methods 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 port. Clearing this bit to 0 makes the pin
an input port.
