Burst Mode On McBSP - denis rouvre - Jul 31 9:58:00 2002

Hi, I'm migrating from 'C549 to 'C5409, Does anyone know if it's possbible to make it work in burst mode (FSM bit ob 'C549). Thanks. Denis |

Denis- Anything you can/did do with BSP, you can do on McBSP. Sometimes, it's a bit tricky and you have to experiment with the numerous bits in the McBSP setup registers. As one example, the McBSP will ignore extra words outside of a frame if you mismatch the frame size (words) with what's actually happening; the BSP has no framesize value and just keeps acquiring. But, in this case you can make the McBSP act like the BSP by setting an "ignore framesync" bit. For burst mode type operation, you might try framesize = 1, and don't ignore framesync. The McBSP will need to see a framesync pulse for every word.
