TAA=B_0x0, DSPW=B_0x0
DMA mode register
| SWR | Software Reset |
| TAA | Transmit Arbitration Algorithm 0 (B_0x0): Fixed priority. In fixed priority, Channel 0 has the lowest priority and the last channel has the highest priority. 1 (B_0x1): Weighted Strict priority (WSP) 2 (B_0x2): Weighted Round-Robin (WRR) |
| DSPW | Descriptor Posted Write 0 (B_0x0): The descriptor writes are always non-posted. 1 (B_0x1): The descriptor writes are non-posted only when IOC (Interrupt on completion) is set in last descriptor. Otherwise, the descriptor writes are always posted. |
| TXPR | Transmit priority |
| INTM | Interrupt Mode |
