9.12.4
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 1, 2, 4 to 6 when 8-bit bus mode is selected, or in
mode 3 or 7, and can be specified as on or off on an individual bit basis.
When a PEDDR bit is cleared to 0 in mode 1, 2, 4 to 6 when 8-bit bus mode is selected, or in
mode 3 or 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 power-on reset, and in hardware standby
mode. The prior state is retained after a manual reset, and in software standby mode.
Table 9.22 summarizes the MOS input pull-up states.
