12-bit threshold limit for mismatch alert. If:
MAXCELL - MINCELL > MSMTCH
then the ALRTMSMTCH alert bit in the STATUS register is set. If the MSMTCH threshold is
set to 0xFFF0, no alert is possible; this immediately clears the alert status. For all other
MSMTCH threshold value changes, the alert status does not change until after the next
measurement scan.
Write ignored; read back 0.
12-bit threshold limit for an undervoltage alert on the AUXIN1 and AUXIN2 inputs. When the
auxiliary analog inputs are used with an NTC thermistor as part of the recommended circuit,
this register can be used to store the overtemperature threshold. This threshold may also be
used as a general undervoltage trip point for the auxiliary inputs. The ALRTTHOT bit in the
STATUS register is set if:
AIN1 OR AIN0 < AINOT
The polarity of this comparison assumes that an NTC thermistor is used in the application
circuit.
Write ignored; read back 0.
