The MCASP functions as a general-purpose audio serial port optimized to the requirements of various audio applications. The McASP module can operate in both transmit and receive modes. The McASP is useful for time-division multiplexed (TDM) stream, Inter-IC Sound (I2S) protocols reception and transmission as well as for an intercomponent digital audio interface transmission (DIT). The McASP has the flexibility to gluelessly connect to a Sony/Philips digital interface (S/PDIF) transmit physical layer component.
Although intercomponent digital audio interface reception (DIR) mode (i.e. S/PDIF stream receiving) is not natively supported by the McASP module, a specific TDM mode implementation for the McASP receivers allows an easy connection to external DIR components (for example, S/PDIF to I2S format converters).
The device have integrated 8 McASP modules (McASP1-McASP8) with:
