STA559BW
Invalid input detect mute enable
Table 44.
Setting the IDE bit enables this function, which looks at the input I
mutes if the signals are perceived as invalid.
Binary output mode clock loss detection
Table 45.
Detects loss of input MCLK in binary mode and will output 50% duty cycle.
LRCK double trigger protection
Table 46.
LDTE, when enabled, prevents double trigger of LRCLK on instable I2S input.
Auto EAPD on clock loss
Table 47.
When active, issues a power device power down signal (EAPD) on clock loss detection.
