Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

31:12 | dma_periph_resv2_fld | RO | 0x0 | |
11:8 | numburstreqbytes |
Number of bytes in a burst type request on the DMA peripheral request. A programmed value of 0 represents a single byte. This should be setup before starting the indirect read or write operation. The actual number of bytes used is 2**(value in this register) which will simplify implementation. |
