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 a PEDDR bit is cleared to 0 (input port setting) with 8-bit bus mode selected in modes 4 to
6, or in mode 7, setting the corresponding PEPCR bit to 1 turns on the MOS input pull-up for the
corresponding pin.
PEPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
9.9.3
Port E pins also function as data bus input/output pins (D7 to D0). If at least one of areas 0 to 7 is
designated as 16-bit bus space in modes 4 to 6, port E pins automatically function as data bus
input/output pins. If all areas are designated as 8-bit bus space in modes 4 to 6, or in mode 7, each
pin in port E functions as an input/output port, and input or output can be specified individually
for each pin. Port E pin functions are shown in table 9.19.
