Notes:

1. During an asynchronous read cycle, each write operation (synchronous or asynchronous) to the same location will automatically

trigger a read operation which updates the read data. Refer to the ProASICPLUS RAM and FIFO Blocks application note for more

information.

2. Violation or RAWRS will disturb access to the OLD data.

3. Violation of RAWRH will disturb access to the NEWER data.
