4, 3

I/O

General purpose input/output pin

Pull-high open-drain

Wake up from sleep mode when the status of the pin

changes.

P65/OSCI

I/O

General purpose input/output pin

External clock signal input

Input pin of XT oscillator

Pull-high open-drain

Wake up from sleep mode when the status of the pin

changes.

P64/OSCO

I/O

General purpose input/output pin

External clock signal input

Input pin of XT oscillator

Pull-high open-drain

Wake up from sleep mode when the status of the pin

changes.

P63//RESET

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.

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.

P60/INT

I/O

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.
