The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated Sound (I2S) protocols, and inter-component digital audio interface transmission (DIT). 8.14.1 McASP Device-Specific Information The device includes six multichannel audio serial port (McASP) interface peripherals (McASP0, McASP1, McASP2, McASP3, McASP4, and McASP5). The McASP module consists of a transmit and receive section. On McASP0/1, these sections can operate completely independently with different data formats, separate master clocks, bit clocks, and frame syncs or, alternatively, the transmit and receive sections may be synchronized. On McASP2, McASP3, McASP4, and McASP5, the transmit and receive sections must always be synchronized. The McASP module also includes shift registers that may be configured to operate as either transmit data or receive data. The transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM) synchronous serial format or in a digital audio interface (DIT) format where the bit stream is encoded for S/PDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP peripheral supports the TDM synchronous serial format. The McASP module can support one transmit data format (either a TDM format or DIT format) and one receive format at a time. All transmit shift registers use the same format and all receive shift registers use the same format; however, the transmit and receive formats need not be the same. Both the transmit and receive sections of the McASP also support burst mode, which is useful for non-audio data (for example, passing control information between two devices). The McASP peripheral has additional capability for flexible clock generation and error detection/handling, as well as error management. The device McASP0 and McASP1 modules have up to 10 serial data pins, while McASP2, McASP3, McASP4, and McASP5 are limited to up to four serial data pins each. The McASP FIFO size is 256 bytes and two DMA and two interrupt requests are supported. Buffers are used transparently to better manage DMA, which can be leveraged to manage data flow more efficiently. For more detailed information on and the functionality of the McASP peripheral, see the Multichannel Audio Serial Port (McASP) chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 8.14.2 McASP0, McASP1, McASP2, McASP3, McASP4, and McASP5 Peripheral Registers Descriptions Table 8-77.
