Description
A 1 masks the OOL bit from generating an interrupt on the SMBALERT output. The OOL
bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 7 value from generating an interrupt on the SMBALERT
output. The R1T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 6 value from generating an interrupt on the SMBALERT
output. The R2T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 5 value from generating an interrupt on the SMBALERT
output. The R3T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 4 value from generating an interrupt on the SMBALERT
output. The R4T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 3 value from generating an interrupt on the SMBALERT
output. The R5T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 2 value from generating an interrupt on the SMBALERT
output. The R6T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 1 value from generating an interrupt on the SMBALERT
output. The R7T bit is set as normal in the status register for out-of-limit conditions.
Description

The Fan 3 bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Fan 2 value from generating an interrupt on the SMBALERT output.
The Fan 2 bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Fan 1 value from generating an interrupt on the SMBALERT output.
The Fan 1 bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the NORM bit from generating an interrupt on the SMBALERT output.
The NORM bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 10 value from generating an interrupt on the SMBALERT
output. The R10T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 9 value from generating an interrupt on the SMBALERT
output. The R9T bit is set as normal in the status register for out-of-limit conditions.
A 1 masks the Temperature 8 value from generating an interrupt on the SMBALERT
output. The R8T bit is set as normal in the status register for out-of-limit conditions.
