5.12.7. Ordering Model
The following describes the required behavior for the device non-bufferable memory type:
- Write response must be obtained from the final destination.
- Read data must be obtained from the final destination
- Transaction characteristics must not be modified.
- Reads must not be pre-fetched. Writes must not be merged.
- Non-modifiable read and write transactions.
(AWCACHE[1] = 0 or ARCACHE[1] = 0) from the same ID to the same subordinate must remain ordered. The interconnect always provides responses in the same order as the commands issued. subordinates that support reordering provide a constant transaction ID to prevent reordering. AXI subordinates that do not reorder are provided with transaction IDs, which allows exclusive accesses for such subordinates.
