Notes:
1. Min and Max times are indicated to allow increased valid data time as shown by dashed lines.
2. 2.State change of RDEMPTY shown below is reference only. Actual change would indicate no Data 3 available.
3. 3.Valid applies after first access. First access is async with following as sync accesses.
