I'm still looking into this, will update the thread by tommorow.

Chen,

Multichannel mode should support 8/12/16/20/32 bit wide data sizes. 

I think what you want to do in terms of 2 receive and 8 transmit should be possible with the RCERx and XCERx registers.

This app notes goes into implementation detail for multi-channel mode; even though it is written for the C6000 DSP, the McBSP is the same on the C2000 devices.

Hi Matthew,

While my question is whether receive can support 8 partitions?

Thanks!

Johnson,

I'm not sure I understand what is meant by partitions C-H.  From the documentation there are only 2 partitions: A(lower 16-bits) and B(upper 16-bits).

There are 8 sub-frames, however, each with 16 channels of the 128 channel total.  Each subframe can be independently configured for Rx, Tx, or both.  I assumed your A-H question was referring to the subframes, in which case your split can be configured as you want.

Let me know if I'm still mis-understanding.

Best,

Matthew
