10.10.3 Port E Register (PORTE)
PORTE shows port E pin states. This register cannot be modified.

If a port E read is performed while PEDDR bits are set
to 1, the PEDR values are read. If a port E read is
performed while PEDDR bits are cleared to 0, the pin
states are read.

Note: * Determined by the states of pins PE7 to PE0.
10.10.4 Port E Pull-Up MOS Control Register (PEPCR)
PEPCR controls the on/off state of port E input pull-up MOS.
Bit Bit Name Initial Value R/W Description
7 PE7PCR 0 R/W
6 PE6PCR 0 R/W
5 PE5PCR 0 R/W
4 PE4PCR 0 R/W
3 PE3PCR 0 R/W
2 PE2PCR 0 R/W
1 PE1PCR 0 R/W
When a pin is specified as an input port, setting the
corresponding bit to 1 turns on the input pull-up MOS
for that pin.
