Description
2.5 V = 1, masks SMBALERT for out-of-limit conditions on the 2.5 V channel.
V CCP = 1, masks SMBALER T for out-of-limit conditions on the V CCP channel.
V CC = 1, masks SMBALERT for out-of-limit conditions on the V CC channel.
5 V = 1, masks SMBALERT for out-of-limit conditions on the 5 V channel.
RIT = 1, masks SMBALER T for out-of-limit conditions on the Remote 1 temperature channel.
LT = 1, masks SMBALERT for out-of-limit conditions on the local temperature channel.
R2T = 1, masks S MBALERT for out-of-limit conditions on the Remote 2 temperature channel.
OOL = 1, masks SMBALERT for any out-of-limit condition in Status Register 2.

OVT = 1, masks SMBALERT for overtemperature THERM conditions.
FAN1 = 1, masks SMBALERT for a Fan 1 fault.
FAN2 = 1, masks SMBALERT for a Fan 2 fault.
FAN3 = 1, masks SMBALERT for a Fan 3 fault.
If Pin 14 is configured as TACH 4 , F4P = 1 masks SMBALERT for a Fan 4 fault.
If Pin 14 is configured as THERM, F4P = 1 masks SMBALERT for an exceeded THERM timer limit.
If Pin 14 is configured as GPIO, F4P = 1 masks SMBALERT when GPIO is an input and GPIO is
asserted.
