The MCASP receive formatting unit consists of three stages:
Figure 12-271 shows the receive format unit (RFU).
The MCASP receiver supports serial formats of:
Hardware support for these serial formats comes from the programmable options in the receive bitstream format register - MCASP_RFMT:
As shown on Figure 12-271, the data processed in the RFU can be output to host CPU through the configuration port (CFG) or the data port (DATA). The selection is made through the MCASP_RFMT[3] RBUSEL bit. According to port type selected, data transfer has different behaviour. For more details, refer to the Section 12.5.2.3.11.1.3, Transfers Through the DATA Port, and Section 12.5.2.3.11.1.4, Transfers Through the Configuration (CFG) Bus.
