Burst Mode On McBSP

Started by denis rouvre July 31, 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.
