All registers are read/write. See the following bit definition tables for bit assignment information. The de-
fault state of each bit after a power-up sequence or reset is listed in each bit description.
Default = 0
0 - CS8416
1- DSP Header
Function:
Default = 0
0 - Disabled
1- Enabled
Function:
Default = 10
Function:
This bit selects the clock source for the PCM2TDM (P2T) converter. It also selects the data source
for Slot 1-4 (see Figure 5 on page 12) of the TDMer.
This bit powers down the TDMer.
This MUX selects the data lines from the DSP Header, the ADC and the TDM Stream from the TDMer
(see Figure 4 on page 11).
