8.5.24 Status Register 2

Event status register 2.This register is accessible only through the SMBus.

Note: All status bits in this register are reset when START bit of the Configuration register is reset.

Location: 42h

Type:

5V_ERR. Is set to 1 when 5V input voltage is less than the limit set in the corresponding Low Limit register

(see Section 8.5.33 on page 169) or greater than the limit set in the corresponding High Limit register (see

Section 8.5.34 on page 170). Once set, the bit is updated again only after this register is read.

0: Voltage does not exceed any respective limit (default)

1: Voltage exceeds a respective limit

3.3V_ERR. Is set to 1 when 3.3V input voltage is less than the limit set in the corresponding Low Limit

(see Section 8.5.32 on page 169). Once set, the bit is updated again only after this register is read.

0: Voltage does not exceed any respective limit (default)

1: Voltage exceeds a respective limit

Vccp_ERR. Is set to 1 when Vccp input voltage is less than the limit set in the corresponding Low Limit

(see Section 8.5.30 on page 168). Once set, the bit is updated again only after this register is read.

0: Voltage does not exceed any respective limit (default)

1: Voltage exceeds a respective limit

2.5V_ERR. Is set to 1 when 2.5V input voltage is less than the limit set in the corresponding Low Limit

(see Section 8.5.28 on page 168). Once set, the bit is updated again only after this register is read.

0: Voltage does not exceed any respective limit (default)

1: Voltage exceeds a respective limit

Description

DEV2_Fault (Device 2 Fault). Is set to 1 when a communication problem with the optional LM95010 device

occurs. Once set, the bit is updated again only after this register is read.

0: The optional LM95010 device does not exist or exists with valid communication (default)

1: A communication problem with LM95010

RD_Fault (Remote Diode Fault). Is set to 1 when there is a physical connection fault in one of the Remote

Diodes of the Temperature Zones occur (for LM96011: Zone1; for LM96010 or LM96012: Zone1 or Zone3).

Once set, the bit is updated again only after this register is read.

0: Proper connection of Remote Diode (default)

1: Remote Diode connection fault

FAN4_STALL. Is set to 1 when Fan 4 is either stalled or running at low speed (according to the FSTLMD bit in

the associated Extended FANPWM Control register; see Section 8.5.85 on page 190). Once set, the bit is

updated again only after this register is read.

0: Fan operating normally (default)

1: Fan is either stalled or running at low speed
