8.4.1.7 CHANNEL_x_BUFFER_A_TRANSFER_COUNT Register Bit Definition
| Bit Number | Name | Reset Value | Description |
|---|---|---|---|
| [31:16] | Reserved | 0 | Software should not rely on the value of a reserved bit. To provide compatibility with future products, the value of a reserved bit should be preserved across a read-modify-write operation. |
| [15:0] | BUF_A_COUNT | 0 | Number of remaining transfers to be completed between source and destination for buffer A for this channel. This field is decremented after every DMA transfer cycle. Writing a non-zero value to this register causes the DMA to start. This must be the last register written by firmware when setting up a DMA transfer. |
