Function:
This MUX selects the data lines from the ADC’s and the external ADC. The last 4 selections are de-
multiplexed from the TDM stream of SDOUT (see Figure 5 on page 12).
5.4.2 OMCK/LRCK RATIO SELECT (OMCK 128/256
FS)
Default = 0
0 - 256 Fs
1 - 128 Fs
Function:
Selects the MCLK/LRCK ratio of the CS8406 transmitter.
5.4.3 LEFT-JUSTIFIED OR I
²S INTERFACE FORMAT (I²S/LJ)
Default = 0
0 - Left Justified
1 - I
²S
Function:
Selects either I
²S or Left Justified interface format for the CS8406.
5.5 CS8416 CONTROL (ADDRESS 05H)
5.5.1 RESET (RST
)
Default = 1
0 - CS8416 held in reset
1 - CS8416 taken out of reset
Function:
This bit is used to reset the CS8416 and is held low for 300 µs upon FPGA initialization. It is also
pulled low for 300 µs whenever registers 05h[3:1] change.
5.5.2 MASTER/SLAVE SELECT (M/S
)
Default = 1
0 - Slave
1 - Master
Function:
Selects master/slave mode for the CS8416 and configures the internal routing buffers. Pin 6 (RST
