‘D1 = 1, D0 = 0 channel 2 input, monitors input voltage of battery regulator
‘D1 = 1, D0 =1 channel 3 input, monitors battery charging current
‘Note: channel 0 is usually jumpered to CN3 term2 for monitoring battery voltage
‘Note: channel 2 tracks main power input when greater than battery voltage
‘Note: channel 2 approx. 0.6V less than battery voltage when main input less than battery
voltage.
