The THERM Limit Registers are used to set the threshold for the software inputs to the Critical /
Thermal Shutdown circuitry. If the measured channel is linked to the Critical / Thermal Shutdown
circuitry and meets or exceeds this limit, then the SYS_SHDN pin will be asserted.
The External Diode Fault Register indicates which of the external diodes caused the FAULT bit in the
Status Register to be set. These bits are cleared when read if the error condition has been removed.
Bit 7 - E7FLT - This bit is set if the External Diode 7 channel reported a diode fault.
Bit 6 - E6FLT - This bit is set if the External Diode 6 channel reported a diode fault.
Bit 5 - E5FLT - This bit is set if the External Diode 5 channel reported a diode fault.
Bit 4 - E4FLT - This bit is set if the External Diode 4 channel reported a diode fault.
Bit 3 - E3FLT - This bit is set if the External Diode 3 channel reported a diode fault.
Bit 2 - E2FLT - This bit is set if the External Diode 2 channel reported a diode fault.
Bit 1 - E1FLT - This bit is set if the External Diode 1 channel reported a diode fault.
The TRIP_SET Reading Register stores the voltage measured on the TRIP_SET pin. The bit weighting
represents mV above 0V.
