PRODUCTION DATA
The AL bit is a read-only function. Reading the AL bit provides information about the comparator mode status. The state of the POL bit inverts the polarity of data returned from the AL bit. When the POL bit equals 0, the AL bit reads as 1 until the temperature equals or exceeds T(HIGH) for the programmed number of consecutive faults, causing the AL bit to read as 0. The AL bit continues to read as 0 until the temperature falls below T(LOW) for the programmed number of consecutive faults, when the device again reads as 1. The status of the TM bit does not affect the operation of the AL bit.
