Register 10: DMA Channel Useburst Set (DMAUSEBURSTSET), offset 0x018
Each bit of the DMAUSEBURSTSET register represents the corresponding DMA channel. Writing
a 1 disables the peripheral's single request input from generating requests, and therefore only the
peripheral's burst request generates requests. Reading the register returns the status of useburst.
When there are fewer items remaining to transfer than the arbitration (burst) size, the controller
automatically clears the useburst bit to 0. This enables the remaining items to transfer using single
requests. This bit should not be set for a peripheral's channel that does not support the burst request
model.
Refer to “Request Types” on page 183 for more details about request types.
