ALCRLS
ALC and Excursion Limiter Release Time
Sets the release time for both the ALC and Excursion Limiter. See the Automatic Level Control
section for ALC release times. Excursion limiter release time is defined as the time required to
slide from the high corner frequency to the low corner frequency.

DHPTH
Excursion Limiter Threshold
Measured at the Class D speaker amplifier outputs. Signals above the threshold use the upper
corner frequency. Signals below the threshold use the lower corner frequency. VBAT must
correctly reflect the voltage of SPKLVDD to achieve accurate thresholds.
000 = 0.34VP
001 = 0.71VP
010 = 1.30VP
011 = 1.77VP
100 = 2.33VP
101 = 3.25VP
110 = 4.25VP
111 = 4.95VP
