    XOR Test
    R/W
    Set this bit to 1 to enable the XOR connectivity test.
    2
    Enable Remote 2 THERM
    Events
    R/W
    This bit enables THERM
     assertions as an output. Functions when the THERM
     timer
    is enabled and the Remote 2 temperature exceeeds its THERM
     limit.
    1
    Enable Remote 1 THERM
    Events
    R/W
    This bit enables THERM
     assertions as an output. Functions when the THERM
     timer
    is enabled and the Remote 1 temperature exceeeds its THERM
     limit.
    0
    Enable Local THERM
    Events
    R/W
    This bit enables THERM
     assertions as an output. Functions when the THERM
     timer
    is enabled and the local temperature exceeeds its THERM
     limit.

    Conversion Rate
    R/W
    These four bits set the conversion rate of the ADM1034. Changing these bits does
    not update the conversion rate until the start of the next round robin.
    0000 = 0.0625 conversions/second
    0001 = 0.125 conversions/second
    0010 = 0.25 conversions/second
    0011 = 0.5 conversions/second
