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.
