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. |
RW | 0x0 |
7:4 | dma_periph_resv1_fld | RO | 0x0 | |
3:0 | numsglreqbytes | Number of bytes in a single 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. |
