/* check_status() is used to read all of the ADC values going into the micro.
These include the battery voltage, the X and Y tilt values from the
accelerometer. Port A is also used as a digital IO port and aswell
as taking the anologue tilt readings, a digital version can also be
obtained by pooling the two digital input pins, 4 and 5 and using a
timer counter. Port A also control the Serial IC and the Charge pump.
