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 volt-

ages 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.
