ADC Control - Address 04h
Functional Mode (Bits 7:6)
Function:
Selects the required range of sample rates.
Digital Interface Format (Bit 4)
Function:
The required relationship between LRCK, SCLK and SDOUT is defined by the Digital Interface Format
bit. The options are detailed in
Mute (Bit 2)
Function:
When this bit is set, the serial audio output of the both channels is muted.
High-Pass Filter Freeze (Bit 1)
Function:
When this bit is set, the internal high-pass filter is disabled.The current DC offset value will be frozen and
continue to be subtracted from the conversion result. See
page 24.
Master / Slave Mode (Bit 0)
Function:
This bit selects either master or slave operation for the serial audio port. Setting this bit selects Master
Mode, while clearing this bit selects Slave Mode.
