Power control circuit that lets MCU shut itself off
Without 10K in series, pin 1032 would be pulled to Vbat even before the power supply is on. That will consequently pull +3V power line up through the inherent cmos diode, with unpredictible results. 10K seems to be high enough to prevent this happen.

1K prevents logic level to exceede the pin limit. Without the resistor, voltage with button down would be Vbat, which may be higher then absolute maximum ratings. 1K and 10K create 10:11 divider, bringing Vbat into acceptable range.

As downside, this circuit draws power (cca. 0.4mA) all the time the button is pressed, even when procesor decide to shut itself off, so I'd rather use 100K/10K resistors.
