Data Sheet
specified in this register, analog clipping may occur within the
range of possible digital codes.
FAULT DETECTION AND RECOVERY
Three fault conditions are detected by the
detection system: left channel overcurrent, right channel
overcurrent, and overtemperature. When any of these is
detected, the amplifier shuts down and a read-only I
to indicate the cause of the shutdown. The OC_L, OC_R, and
OT fault indicators are Bit 7, Bit 6, and Bit 5 (respectively) of
Register 0x08.
An autorecovery feature can be enabled for temperature faults,
current faults, or both, depending on the state of ARCV (Bit 1
and Bit 0 of Register 0x08).

If autorecovery is enabled, the amplifier waits a short time
(10 ms, 20 ms, 40 ms, or 80 ms) and attempts to recover. The
recovery delay is set by AR_TIME (Bit 7 and Bit 6 of Register 0x09).
The maximum number of consecutive recovery attempts can be
set to one, three, seven, or unlimited attempts; this number is
set by MAX_AR (Bit 3 and Bit 2 of Register 0x08).
If the autorecovery feature is disabled or the maximum number
of attempts has been reached, the amplifier remains shut down
until a software reset or manual fault recovery attempt occurs.
The manual fault recovery is triggered by setting the write-only
bit, MRCV (Bit 4 of Register 0x08).
