Description
2.5 V = 1, masks SMBALERT for out-of-limit conditions on the 2.5 V channel.

5 V = 1, masks SMBALERT for out-of-limit conditions on the 5 V channel.
RIT = 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.
2.5 V LSBs. Holds the 2 LSBs of the 10-bit 2.5 V measurement.
5 V LSBs. Holds the 2 LSBs of the 10-bit 5 V measurement.
Description
When Pin 21 is configured as a 12 V input, 12V/VC = 1 masks SMBALERT for out-of-limit conditions
on the 12 V channel. When Pin 21 is programmed as VID5, this bit masks an SMBALERT, if the VID5
VID code bit changes.
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.
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.
