EPDD[7:0] — Edge Port Data Direction Bits

Read:
Write:
Setting any bit in the EPDDR configures the corresponding pin as an
output. Clearing any bit in EPDDR configures the corresponding pin
as an input. Pin direction is independent of the level/edge detection
configuration. Reset clears EPDD[7:0].
To use an EPORT pin as an external interrupt request source, its
corresponding bit in EPDDR must be clear. Software can generate
interrupt requests by programming the EPORT data register when the
EPDDR selects output.
