Micro-port access to the ST-BUS C-Channel information read and write
D7-D0
Data written to this register will be transmitted every frame, in channel 0, if the DEn control bit is set (address 04h).
Received D-Channel data is valid, regardless of the state of DEn. These bits are valid for ST-BUS mode only and are
accessible only when IRQ indicates valid access.

PCM/ANALOG This control bit functions only when loopen is set high. It is ignored when loopen is low.
For loopback operation when this bit is high, the device is configured for digital-to-digital loopback operation. Data on
Din is looped back to Dout without conversion to the analog domain. However, the receive D/A path (from Din to
HSPKR
±
) still functions. When low, the device is configured for analog-to-analog operation. An analog input signal at
M
±
is looped back to the SPKR
±
outputs through the A/D and D/A circuits as well as through the normal transmit A/D
path (from M
±
to Dout).
loopen
When high, loopback operation is enabled and the loopback type is governed by the state of the PCM/ANALOG bit.
When low, loopbacks are disabled, the device operates normally and the PCM/ANALOG bit is ignored.
