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.
Note1
: For the high limits of the voltages, the device is doing a greater than comparison. For the low limits, however, it is doing
a less than or equal comparison.
