Data written to EPDR is stored in an internal register; if any pin of the
port is configured as an output, the bit stored for that pin is driven onto
the pin. Reading EDPR returns the data stored in the register. Reset
sets EPD[7:0].
The read-only EPPDR reflects the current state of the EPORT pins.
Writing to EPPDR has no effect, and the write cycle terminates
normally. Reset does not affect EPPDR.
