17.3 0x01 RemainingCapacityAlarm()
This read- or write-word function sets or gets a low-capacity alarm threshold value. The default value for
RemainingCapacityAlarm is stored in Rem Cap Alarm. If RemainingCapacityAlarm() is set to 0, the alarm
is disabled. If RemainingCapacity() < RemainingCapacityAlarm(), the [RCA] flag is set and the bq78350-
R1 sends an AlarmWarning() message to the SMBUS host. If RemainingCapacity() ≥
RemainingCapacityAlarm() and [DSG] is set, the [RCA] flag is cleared. 0 = remaining capacity alarm is
disabled. 1..700 = the remaining capacity limit for [RCA] flag.
