0
General input Pin state
Can write to PEDRH or PEDRL, but it has no
effect on pin state
Other than
general input
Pin state
Can write to PEDRH or PEDRL, but it has no
effect on pin state
1
General output PEDRH or
Value written is output from pin (POE pin = high)^*
PEDRL value
High impedance regardless of PEDRH or PEDRL
value (POE pin = low)^*
Other than
PEDRH or
Can write to PEDRH or PEDRL, but it has no
general output PEDRL value effect on pin state
Note: * Control by the POE pin is only available for high current-output pins (PE9 and PE11 to
PE21).
