Section 8 I/O Ports
Port E MOS Pull-Up Control Register (PEPCR)
PEPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port E on an individual bit basis.
When PEDDR bits are cleared to 0 (input port setting) in mode 4, 5, or 6 with 8-bit bus mode
selected, or in mode 7, setting the corresponding PEPCR bits to 1 turns on the MOS input pull-up
for the corresponding pins.
PEPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
8.10.3
Modes 4 to 6 * : In modes 4 to 6, when 8-bit access is designated and 8-bit bus mode is selected,
port E pins are automatically designated as I/O ports. Setting PEDDR bits to 1 makes the
corresponding port E pins output ports, while clearing the bits to 0 makes the pins input ports.
When 16-bit bus mode is selected, the input/output direction specification by PEDDR is ignored,
and port E is designated for data I/O.
Port E pin functions in modes 4 to 6 are shown in figure 8.21.
