Set to 1, enable serial interface timeout function. (25ms). Set to 0, disable.
These bits are unused and always set to 0
This bit is unused and always set to 1
Set to 1, T1 temperature exceeds high limit will not generate an ALERT.
Set to 0, T1 temperature exceeds high limit will generate an ALERT.
Set to 1, T1 temperature goes below low limit will not generate an ALERT.
Set to 0, T1 temperature goes below low limit will generate an ALERT.
Set to 1, T2 temperature exceeds high limit will not generate an ALERT.
Set to 0, T2 temperature exceeds high limit will generate an ALERT.
Set to 1, T2 temperature goes below low limit will not generate an ALERT.
Set to 0, T2 temperature goes below low limit will generate an ALERT.
This bit is unused and always set to 1
