DMA_DST_SIZE (OSPI) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| Reserved | 31:29 | razRead as zero | 0x0 | RESERVED. Return 0 when read. Writes ignored. |
| SIZE | 28:2 | rwNormal read/write | 0x0 | Specifies the number of 4-byte words the DMA will transfer from stream to memory Size is word aligned, so this field is only 27-bits. (2 lsbs are 0) The action of writing to this register starts a DMA transfer of length SIZE, moving data from the stream interface to ADDR. In this case, it indicates the total payload that the DMA will move from stream to memory. After the DMA has started, this field will dynamically change under DMA control to reflect the remaining payload size that the DMA must still complete. Whenever a BRESP is returned from memory, the SIZE will decrement by 1. |
| Reserved | 1:0 | razRead as zero | 0x0 | RESERVED. Return 0 when read. Writes ignored. |
