D7: ALERT mask: When set to “1” ALERT interrupts are masked.

D6: RUN/STOP: When set to “1” SHUTDOWN is enabled.

D5: is not defined and defaults to “0”.

D4: Remote T_CRIT_A mask: When set to “1” a diode temperature reading that exceeds T_CRIT_A setpoint will not activate the

T_CRIT_A pin.

D3: is not defined and defaults to “0”.

D2: Local T_CRIT_A mask: When set to “1” a Local temperature reading that exceeds T_CRIT_A setpoint will not activate the

T_CRIT_A pin.

D1: is not defined and defaults to “0”.

D0: Fault Queue: when set to “1” three consecutive remote temperature measurements outside the HIGH, LOW, or T_CRIT

setpoints will trigger an “Outside Limit” condition resulting in setting of status bits and associated output pins..
