Description

BURST_TX

0x0

Defines the type of DMA request generated by the DMA TX

interface.

0: Single request mode. Transfers a single data (one byte) in

the TX FIFO.

1: Burst request mode. Transfers a programmed burst of data

according to DBSIZE_TX field.

When the burst mode is programmed, the DMA transfer can

be completed by one or more single requests as required.
