Notes:
1. All inputs except OE must meet setup and hold times for the Low-to-High transition of clock (CLK).
2. Wait states are inserted by suspending burst.
3. X means don't care. WRITE=L means any one or more byte write enable signals (BW1-BW4) and BWE are LOW or GW is
4. For a Write operation following a Read operation, OE must be HIGH before the input data required setup time and held HIGH
5. ADSP LOW always initiates an internal READ at the Low-to-High edge of clock. A WRITE is performed by setting one or more
