DE-EMPHASIS MODE
Setting the DEEMPH register bit puts the digital filters into de-emphasis mode:

DESCRIPTION
De-emphasis mode select:
0: De-emphasis Off
1: De-emphasis On
POWERDOWN MODE
Setting the PWDN register bit immediately connects all outputs to V
MID
and selects a low power
mode. All trace of the previous input samples is removed, but all control register settings are
preserved. When PWDN is cleared again the first 16 input samples will be ignored, as the FIR
will repeat it's power-on initialisation sequence.
