Notes:
1. This behavior is valid for Access Timed Output and Pipelined Mode Output. The table shows the timings of an Access Timed Output.
2. In asynchronous write and synchronous read access to the same location, the new write data will be read out if the active write
3. A setup or hold time violation will result in unknown output data.
