Function

Power supply.

* General purpose I/O 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.

* General purpose I/O 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.

* If set as /RESET and remain at logic low, the device will be under reset.

* If P63 is set and kept at logic “high,” the oscillator will oscillate.

* If kept at logic low, it cannot oscillate.

* Wake up from sleep mode when the status of the pin changes.

* Voltage on /RESET must not exceed Vdd during the normal mode.

* Pull_high is on if defined as /RESET.

* P63 is input pin only

* General purpose I/O pin.

* Pull_high/open_drain/pull_down.

* Wake up from sleep mode when the status of the pin changes.

* External Timer/Counter input.

* General purpose I/O pin.

* Pull_high/open_drain/pull_down.

* Wake up from sleep mode when the status of the pin changes.

* Schmitt Trigger input during programming mode

* General purpose I/O pin.

* Pull_high/open_drain/pull_down.
