Specify the number of 16-bit words in a burst, from 1 to
32. The DMA module must complete a burst before it
can service the next channel.
Set the Burst value appropriately for the peripheral the
DMA module is servicing. For the ADC, the value equals
the number of ADC registers being used, up to 16. For
multichannel buffered serial ports (McBSP), which lack
FIFOs, the value is 1. For RAM, the value can range
from 1 to 32.
This parameter corresponds to bits 4-0 (BURSTSIZE) in
the Burst Size Register (BURST_SIZE).
Note This parameter is based on a 16-bit word size. If
you set Data size to
32 bit,doublethevalueofthis
parameter.
Note When you select Use DMA (with C28x3x) the
C280x/C28x3x ADC block, the value assigned to Burst
equals the ADC block Number of conversions (NOC)
multip lied by a value for the A D C block Conversion
mode (CVM). Burst = NOC * CVM
If Conversion mode is
Sequential,CVM=1. If
Conversion mode is
Simultaneous, CVM = 2.
Forexample,Burst=6ifNOC=3andCVM=2(6=3
*2).
