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. During synchronous write and synchronous read access to the same location, the new write data will be read out if the active write
clock edge occurs before or at the same time as the active read clock edge. The negative setup time insures this behavior for WCLKS
and RCLKS driven by the same design signal.
3. If WCLKS changes after the hold time, the data will be read.
4. A setup or hold time violation will result in unknown output data.
