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.
2. Violation of RAWCLKS will disturb access to OLD data.
3. Violation of RAWCLKH will disturb access to NEWER data.
