Test Register = 1 and Bit 7 of
VID Register = 0, then setting
this bit to 1 configures tHhe
Offset Register to the internal
temperature channel. Clearing
this bit configures the Offset
Register to the external
temperature channel.

For the high limits of the voltages, the device is doing a greater-than compari-
son. For the low limits, however, it is doing a less-than or equal comparison.
