Table 42. Register 0x72. Interrupt Mask Register 1 (Power-On Default = 0x00).
Bit Name Read/Write Description
[7] Not in use Read/Write Not in use. Write 0 to this bit.
[6] R7T Read/Write 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.
[5] R6T Read/Write 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.
[4] R5T Read/Write 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.
[3] R4T Read/Write 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.
[2] R3T Read/Write 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.
[1] R2T Read/Write 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.
[0] R1T Read/Write 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.
Table 43. Register 0x73. Interrupt Mask Register 2 (Power-On Default = 0x00).

SMBALERT
output.
The Fan 4 bit is set as normal in the status register for out-of-limit conditions.
[6] Fan 3 Read/Write A 1 masks the Fan 3 value from generating an interrupt on the
SMBALERT
output.
The Fan 3 bit is set as normal in the status register for out-of-limit conditions.
[5] Fan 2 Read/Write 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.
[4] Fan 1 Read/Write 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.
[3] Daisy chain Read/Write A 1 masks the pulsing of the
SMBALERT
while enabling daisy chain, writing to Bit [7]
Register 0x40.
[2] R10T Read/Write 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.
[1] R9T Read/Write 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.
[0] R8T Read/Write 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.
