Bit coded as follows:
2-0
Over Temp alarm threshold bit in
AlarmWarning register, 0.1 C increments,
Coded value = (Celsius*10+200).
When the temperature exceeds
HighTempAlarm, the OverTempAlarm
becomes active. If charging, the
TerminateChargeAlarm also becomes
active.
Frequency of charging condition
broadcasts.
Bus-on silence period for messages.
SBData value for RemCapAl. The SBData
specification requires a default of
DesignCapacity/10 for this value. When
the Remaining Capacity calculation
reached the value of RemCapAl, the
REMAINING_CAPACITY_ALARM bit will
be set in the BatteryStatus register, and an
alarm broadcast to the host will occur if
alarm broadcasts are enabled.
SBData value for RemTimeAl. SBData
requires a default of 10 minutes for
this value. When the RunTimeToEmpty
calculation reaches the value of
RemTimeAl, the
REMAINING_TIME_ALARM bit in
BatteryStatus will be set.
SMBus address of the battery.
Cell voltage when the battery sends
TERMINATE_CHARGE_ALARM. This is a
voltage higher than end-of-charge voltage
that will trigger a terminate charge alarm in
case EOC is not responded to by the
charger.
