8.15.6
Port E and port F 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 8.10 is a summary of the input pull-up MOS states.

Legend
Off:
On/Off: On when PEDDR = 0 and PEODR = 1 (PFDDR = 0 and PFODR = 1); otherwise off.
8.16
Port G is an 8-bit I/O port. Port G pin functions are the same in all operating modes. The output
type of port G is NMOS open-drain.
8.16.1
PGDDR selects input or output for the pins of port G on a bit-by-bit basis.
