9.12.4
Port E has a on-chip MOS input pull-up function that can be controlled by software. This MOS input pull-up function can
be used in modes 4 to 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 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.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.

Legend:
OFF:
ON/OFF: On when PEDDR = 0 and PEPCR = 1; otherwise off.
