General purpose input/output pin
Pull-high/Pull-down/open-drain
Wake up from sleep mode when the status of the pin changes.
Schmitt Trigger input during programming mode.
External interrupt pin triggered by a falling edge.
General purpose input/output pin
Pull-high/Pull-down/open-drain
Wake up from sleep mode when the status of the pin changes.
Schmitt Trigger input during programming mode
General purpose input/output pin
External Timer/Counter input
Pull-high/Pull-down open-drain
Wake up from sleep mode when the status of the pin changes.
P63 is input pin only
Internal Pull-high is On if defined as /RESET.
If set as /RESET and remains at logic low, the device will be
reset.
Wake-up from sleep mode when pin status changes.
Voltage on /RESET must not exceed Vdd during normal mode.
