High temperature, remote
TEMP1 > T_SET1
Set S1 in CONFIG, assert /INT
High temperature, local
TEMP0 > T_SET0
Set S0 in CONFIG, assert /INT
Low temperature, remote
TEMP1 < T_HYST1
Set S1 in CONFIG, assert /INT
Low temperature, local
TEMP0 < T_HYST0
Set S0 in CONFIG, assert /INT
Over-temperature, remote
TEMP1 > CRIT1
Set CRIT in CONFIG, assert /CRIT
NOT Over-temperature, remote TEMP < nCRIT1
Clear CRIT in CONFIG, de-assert /CRIT
Diode Fault
T1 open or T1 shorted to VDD or GND
Set CRIT and S1 in CONFIG, assert /INT
and /CRIT***
* CONDITION must be true for Fault_Queue conversions to be recognized
** Assumes interupts enabled
*** Assumes that T_SET1 and CRIT1 are set to any value less than +127° C = 7F_h = 0111 1111_b.
