Description

DEV2_EV (Device 2 Event). Is set to 1 when a communication event with the optional LM95010 device occurs.

0: No communication event occurred since the last time this bit was cleared (default)

1: Communication event occurred

RD_EV (Remote Diode Event). Is set to 1 when a physical connection event on one of the Remote Diodes of

the Temperature Zones occurs (For LM96011: Zone1; for LM96010 or LM96012: Zone1 or Zone3).

0: No Remote Diode event occurred since the last time this bit was cleared (default)

1: Remote Diode physical connection event occurred

FAN4_EV. Is set to 1 when a Fan Tachometer Reading 4 monitoring event occurs.

0: No fan state change from the last time this bit was cleared (default)

1: Fan changed state from the last time this bit was cleared

FAN3_EV. Is set to 1 when a Fan Tachometer Reading 3 monitoring event occurs.

0: No fan state change from the last time this bit was cleared (default)

1: Fan changed state from the last time this bit was cleared

FAN2_EV. Is set to 1 when a Fan Tachometer Reading 2 monitoring event occurs.

0: No fan state change from the last time this bit was cleared (default)

1: Fan changed state from the last time this bit was cleared

FAN1_EV. Is set to 1 when a Fan Tachometer Reading 1 monitoring event occurs.

0: No fan state change from the last time this bit was cleared (default)

1: Fan changed state from the last time this bit was cleared

DEV1_EV (Device 1 Event). Is set to 1 when a communication event with the LM96011, LM96010 or LM96012

occurs.

0: No communication event occurred since the last time this bit was cleared (default)

1: Communication event occurred

12V_EV. Is set to 1 when a 12V input voltage monitoring event occurs.

0: No state change from the last time this bit was cleared (default)

1: Voltage changed state from the last time this bit was cleared
