Port E MOS Input Pull-Up States

Port E has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in 8-bit bus mode. MOS input pull-up can be specified as on or
off on a bit-by-bit basis. In 8-bit bus mode, when a PEDDR bit is cleared to 0, setting the
corresponding PEPCR bit to 1 turns on the MOS input pull-up for that pin.
Table 9.6 summarizes the MOS input pull-up states.
