8.14.6 Input Pull-Up MOS in Ports C and D
Port C and port D have an on-chip input pull-up MOS function that can be controlled by software.
This input pull-up MOS function can be switched on or off on a bit-by-bit basis.
Table 8.9 is a summary of the input pull-up MOS states.

Off: Input pull-up MOS is always off.
On/Off: On when PCDDR = 0 and PCODR = 1 (PDDDR = 0 and PDODR = 1); otherwise off.
8.15 Ports E, F
Port E and port F are two sets of 8-bit I/O ports. The pins of ports E and F have the same functions
in all operating modes.
• 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)
