7.13
Ports E and F are two sets of 8-bit I/O ports. Port F also functions as I/O pins for TMR_X*,
TMR_Y*, TMR_A, and TMR_B. Ports E and F have the following registers.
• Port E data direction register (PEDDR)
• Port E output data register (PEODR)
• Port E input data register (PEPIN)
• Port E Nch-OD control register (PENOCR)
• Port F data direction register (PFDDR)
• Port F output data register (PFODR)
• Port F input data register (PFPIN)
• Port F Nch-OD control register (PFNOCR)
Note: *
7.13.1
PEDDR and PFDDR select input or output for the pins of port E and port F on a bit-by-bit basis.

Description
0: Port E pin is an input pin
1: Port E pin is an output pin
PEDDR has the same address as PEPIN, and if read,
the port E pin states will be returned.
Description
0: Port F pin is an input pin
1: Port F pin is an output pin
PFDDR has the same address as PFPIN, and if read,
the port F pin states will be returned.
