9.15.4
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 modes 4, 5, and 6 when 8-bit bus mode is selected, or in
mode 7, and can be specified as on or off on an individual bit basis.
When a PEDDR bit is cleared to 0 in mode 4, 5, or 6 when 8-bit bus mode is selected, or in mode
7, setting the corresponding PEPCR bit to 1 turns on the MOS input pull-up for that pin.
The MOS input pull-up function is in the off state after a reset, and in hardware standby mode.
The prior state is retained in software standby mode.
Table 9.29 summarizes the MOS input pull-up states.
