3Ch FAN1 Fan Count Limit
Note: It is the number of counts of the internal clock for the Low Limit of the fan speed.
3Dh FAN2 Fan Count Limit
Note: It is the number of counts of the internal clock for the Low Limit of the fan speed.
3Eh-3Fh Reserved
Note: Setting all ones to the high limits for voltages and fans (0111 1111 binary for temperature) means interrupts will never be generated except the case when
voltages go below the low limits.
For voltage input high limits, the device is doing a greater than comparison. For low limits, however, it is doing a less than or equal to comparison.
