The Status Register reports general error conditions. To identify specific channels, refer to Section 5.8,
Section 5.13, and Section 5.14. The individual Status Register bits (except HOTTEST) are cleared
when the appropriate High Limit or Low Limit register has been read or cleared.
Bit 7 - BUSY - This bit indicates that the ADC is currently converting.
Bit 6 - HOTTEST - This bit is set if the REM_HOT bit (see Section 5.17) is set and the hottest channel
changes. This bit is cleared when the register is read.
Bit 4 - HIGH - This bit is set when any of the temperature channels meets or exceeds its programmed
high limit. See the High Limit Status Register for specific channel information (Section 5.13).
Bit 3 - LOW - This bit is set when any of the temperature channels drops below its programmed low
limit. See the Low Limit Status Register for specific channel information (Section 5.14).
Bit 2 - FAULT - This bit is asserted when a diode fault is detected on any of the external diode
channels. See the External Diode Fault Register for specific channel information (Section 5.8).
