7.3.9.12 SSC Direct Access Mode Register

The receiver does not provide the capability to select the channels that will be transferred on the direct link to the Asynchronous Sample Rate Converter (ASRC). The selection is possible in the ASRC.

When the SSC receiver is configured in Device mode (SSC_RCMR.CKO=0), the SSC_RFMR.DATNB field must be configured with the number of data in the received frame. When the SSC transmitter is configured in Device mode (SSC_TCMR.CKO=0), the SSC_TFMR.DATNB field must be configured with the number of data in the transmitted frame.
