R1T = 1 masks SMBALERT 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 SMBALERT 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.
Description
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.
F4P = 1 masks SMBALERT for a Fan 4 fault. If the TACH4 pin is used as the THERM input, this bit
masks SMBALERT for a THERM timer event.
D1 = 1 masks SMBALERT for a diode open or short on a Remote 1 channel.
D2 = 1 masks SMBALERT for a diode open or short on a Remote 2 channel.
