TMS320X281X MCBSP参考指导 The multichannel buffered serial port (McBSP) provides a direct serial interface between a digital signal processor (DSP) and other devices in a system. This reference guide is applicable for theMcBSP found on the TMS320x281x family of processors. This includes all Flash-based, ROM-based, and RAM-based devices within the 281x family. If you have used a McBSP in other TI DSPs, note that there are differences in this implementation, which are outlined in Table 1--1. within the 281x family. If you have used a McBSP in other TI DSPs, note that there are differences in this implementation, which are outlined in Table 1--1.
