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.

0 - Disabled
1- Enabled
Function:
This bit selects the clock source for the PCM2TDM (P2T) converter. It also selects the data source
for Slot 1 (see Figure 5 on page 12) of the TDMer.
This bit also serves as the MSB of the 3:2 data selection MUX’s for slots 2-4 of the TDM Stream (see
Figure 5 on page 12).
This bit selects the data source for the PCM2TDM (P2T) converter. The DSP/CS8416 bit serves as
the MSB of the MUX that selects between OUTx and OUT1.
If the CS8416 is selected as the clock source for the P2T converter, this bit is ignored and the CS8416
SDOUT will be selected as the data source for slots 2-4 (see Figure 5 on page 12).
This bit powers down the TDMer.
