2.0 LM89 Registers
(Continued)
D6: RUN/STOP: When set to “1” SHUTDOWN is enabled.
D5: is not defined and defaults to “0”.
D4: Remote T_CRIT mask: When set to “1” a diode temperature reading that exceeds T_CRIT setpoint will not activate the
T_CRIT_A pin.
D3: is not defined and defaults to “0”.
D2: Local T_CRIT mask: When set to “1” a Local temperature reading that exceeds T_CRIT 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..
