Description
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.
Description
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.
