Mode

The follow ing parameters conﬁgure the DMA channel.

• Enable one shot mode

Enable this parameter to have the DMA channel complete

an entire transfer in response to an interrupt event

trigger. This option allows a single DMA channel and

peripheral to dominate resources, and may streamline

processing, but it also creates the potential for res ource

conﬂicts and delays.

Disable this parameter to have DMA complete one burst

per channel per interrupt.

Note When you select Use DMA (with C28x3x) the

C280x/C28x3x ADC block, this parameter is disabled.

• Sync enable

When Interrupt source is set to SEQ1INT, enable

this parameter to reset the DMA wrap counter when

it receives the ADCSYNC signal from SEQ1INT. This

ensures that the wrap counter and the ADC channels

remain synchronized with each other.

If Interr upt source is n ot set to SEQ1IN T, Sync

enable has no effect.

This parameter corresponds to bit 12 (SYNCE) of the

Mode Register (MODE).

Note When you select Use DMA (with C28x3x) the

C280x/C28x3x ADC block, this parameter is disabled.

• Enable continuous mode
