"Specialized Version" of McBSP in OMAP-L138?

Other Parts Discussed in Thread: OMAP-L138

I found the following statement in the TMS320C674x/OMAP-L1x Processor Multichannel Buffered Serial Port (McBSP) Interface User's Guide (SPRUGJ6C).

 "The primary use for the multichannel buffered serial port (McBSP) is for audio interface purposes. The McBSP is a specialized version of the McBSP peripheral used on other TI DSPs."

Could someone please elaborate on this? I plan to use the McBSP as a high speed data interface with an external serial device. Will it not work in such an application? I could not find anything obvious after a cursory look through the document.

Also, I find this a bit strange since the OMAP-L138 also contains a McASP, whose primary function is for "audio interface purposes".

Thx,

MikeH

    The second sentence ("The McBSP is a specialized version of the McBSP peripheral used on other TI DSPs") can probably be removed without any impact on the information conveyed.

    Can you please provide details on the data rate you are looking for while interfacing with the external serial device?

    McASP is targeted towards audio and have complete support for I2S/AC97.

    Thanks,

    Gaurav,

    I will be interfacing with a 2Mbps serial device which I believe should work fine with the McBSP on the OMAP-L138.

    Thanks,
