SPK_EN_R:
Enable bit for the right-channel amplifier. Amplifier is active when bit is high. This function is
gated by thermal and returns once the IC is below the threshold temperature.
SPK_EN_L:
Enable bit for the left-channel amplifier. Amplifier is active when bit is high. This function is
gated by thermal and returns once the IC is below the threshold temperature
SWS:
Software shutdown control. The device is in software shutdown when the bit is '1' (control, bias
and oscillator are inactive). When the bit is '0' the control, bias and oscillator are enabled.
Fault_L:
This bit indicates that an over-current event has occurred on the left channel with a '1'. This bit
is cleared by writing a '0' to it.
Fault_R:
This bit indicates that an over-current event has occurred on the right channel with a '1'. This
bit is cleared by writing a '0' to it.
Thermal:
This bit indicates a thermal shutdown that was initiated by the hardware with a '1'. This bit is
deglitched and latched, and can be cleared by writing a '0' to it.
NG_EN:
Enable bit for the Noise Gate function. This function is enabled when this bit is high. This
function can only be enabled when the Compression ratio is not 1:1.
