ATTENUATOR CONTROL MODE
Setting the ATC register bit causes the left channel attenuation settings to be applied to both left
and right channel DACs from the next audio input sample. No update to the attenuation registers
is required for ATC to take effect. (The right channels registry settings are preserved.)

BCKIN POLARITY
By default, LRCIN and DIN are sampled on the rising edge of BCKIN and should ideally change
on the falling edge. Data sources which change LRCIN and DIN on the rising edge of BCKIN can
be supported by setting the BCP register bit. Setting BCP to 1 inverts the polarity of BCKIN to the
inverse of that shown in Figure 4, Figure 5, Figure 6, Figure 7 and Figure 8

OUTPUT PHASE REVERSAL
The REV register bit controls the phase of the output signal. Setting the REV bit causes the
phase of the output signal to be inverted.
