7.6.2.7 Channel-3 Bus-Voltage Register (address = 06h) [reset = 00h]
This register stores the bus voltage reading, VBUS, for channel 3. Full-scale range = 32.76V (decimal = 7FF8);
LSB (BD0) = 8mV. Although the input range is 26V, the full-scale range of the ADC scaling is 32.76V. Do not
apply more than 26V.
