VOLTAGE MEASUREMENT

Battery voltage is measured every 440ms on the VIN pin with respect to VSS. Measurements have a 0 to 4.99V

range and a 4.88mV resolution. The value is stored in the voltage register in twoâs complement form and is updated

every 440ms. Voltages above the maximum register value are reported at the maximum value; voltages below the

minimum register value are reported at the minimum value.
