Force powerdown enable for the speaker thermal
algorithm:
0 = Speaker will remain powered up even if the temp
sensor continues to report an overheat condition at
minimum volume (mute)
1 = Speaker will be powered down if the temp sensor
reports an overheat at the minimum volume (mute)
Instant Cut Mode
0 = Both temp sensor status bits used to smoothly
adjust the volume.
1 = Only the high temp sensor status bit will be used to
set the volume. volume will be set to the full volume or
mute (IncStep and DecStep are ignored.)
Increment interval ratio. Determines the ratio between
the speaker volume increment interval and the speaker
volume decrement interval (increment rate is equal to or
slower than decrement rate):
0h = 1:1
1h = 2:1
2h = 4:1
3h = 8:1
Increment step size for the speaker thermal control
algorithm (occurs at the temp sensor polling rate X the
increment interval ratio.)
0h = 0.75dB
1h = 1.5dB
2h = 3.0dB
3h = 6.0dB
Decrement step size for the speaker thermal control
algorithm (occurs at the temp sensor polling rate.)
0h = 3dB
1h = 6dB
2h = 12dB
3h = 24dB
0: Speaker not powered down due to thermal algorithm
1: Speaker has been powered down because overtemp
condition was present even though the speaker was
muted.
Current speaker volume value. If no overheat is being
reported by the temperature sensor, this value should
be equal to the greater of the left or right speaker
volume setting.
