ADT7476A

In this mode, the ADT7476A can only read a single voltage

channel. The selected voltage input is read every 0.7 ms. The

appropriate ADC channel is selected by writing to Bits [7:5]

of the TACH1 minimum high byte register (0x55).

1. In the process of configuring single-channel ADC conversion

mode, the TACH1 minimum high byte is also changed, possibly

trading off TACH1 minimum high byte functionality with

single-channel mode functionality.
