| AWCACHE | 26:24 | rwNormal read/write | 0x0 | Controls the AWCACHE bits of the AXI Write transaction: Bit[24]: AXI AwCache[0] signal. Bit[25]: AXI AwCache[2] signal. Bit[26]: AXI AwCache[3] signal. Note: AXI AwCache[1] signal is always driven to 1. Note: Change this value only when controller is not processing commands. |
| Reserved | 23 | razRead as zero | 0x0 | reserved |

The [TIMEOUT_PRE] field is interpreted as follows: 000: Prescaler enables timer every cycle. 001: Prescaler enables timer every 2 cycles. .. FFF: Prescaler enables timer every 4096 cycles. Note: Change this value only when controller is not processing commands. |
| MAX_OUTS_CMDS | 3:0 | rwNormal read/write | 0x8 | Controls the maximum number of outstanding AXI write commands issued. The field is interpreted as follows: 0: Max of 1 Outstanding Write command allowed 1 to 8: Max of 2 to 9 Outstanding Write commands allowed Note: Change this value only when controller is not processing commands. |
