Asynchronous Write and Synchronous Read to the Same Location
Note: *New data is read if WB
occurs before setup time. The stored data is read if WB occurs after hold time. The plot shows the
normal operation status.

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
signal edge occurs before or at the same time as the active read clock edge. If WB changes to low after hold time, the data will be
read.
3. A setup or hold time violation will result in unknown output data.
