Input Configuration (Address 02h)
Input Source Selection (ADC/SP)
Default = 0
Function:
This bit selects the audio input source.
ADC High-Pass Filter Enable (EnAnHPF)
Default = 1
Function:
Controls the operation of the ADC high-pass filter.
Serial Port Sample Rate (SPRate[1:0]) - Read Only
Function:
Identifies the sample rate of the incoming LRCK signal on the serial audio input port based on the setting
of the ClkFreq[1:0] bits in Register 01h, the frequency of the internal system clock, and the frequency of
the input LRCK signal.
Input Serial Port Digital Interface Format (DIF [2:0])
Default = 000
Function:
Selects the serial audio interface format used for the data in on SDIN. The required relationship between
the Left/Right clock, serial clock and serial data is defined by the Digital Interface Format and the options
are detailed in the section
