a: 1 if charging (accepting power from the AC adapter)
c: 1 if battery is detected
b: 1 if the device is battery-operated
P: 1 if CPU halted (so that the "smart" power supply can shut itself down)

if the device is battery-operated but currently running off of an AC adapter and there is no battery inserted,
the flag would be 1000 0001
the flag would be 0000 1001
