LRCK double trigger protection
Table 35.
Actively prevents double trigger of LRCLK.
Auto EAPD on clock loss
Table 36.
When active will issue a power device power-down signal (EAPD) on clock loss detection.
IC power down
Table 37.
The PWDN register is used to put the IC in a low-power state. When PWDN is 0, the output
begins a soft-mute. After the mute condition is reached, EAPD is asserted to power down
the power stage, then the master clock to all internal hardware except the I
This puts the IC in a very low power consumption state.
External amplifier power down
Table 38.
The EAPD register directly disables/enables the internal power circuitry.
When EAPD = 0, the internal power section is placed in a low-power state (disabled).
