Auxiliary analog
input 0 is outside
one of the set
thresholds
Specifies whether
each cell has
an overvoltage
or undervoltage
condition
Specifies whether
each cell is in an
overvoltage state
Specifies whether
each cell is in an
undervoltage state
The charge-pump
output VDD
fallen below the
undervoltage
threshold
Alarm bus

out of specification
REF pin is
oscillating, most
likely due to an
open-circuit
condition
