Note: 1. The x8 or Byte Address mode is not available.
2. In the x16 organization, the value of the address location of the CFI Query is independent of A1 pad (M58LW064B).
3. Query Data are always presented on the lowest order data outputs (DQ7-DQ0) only. Others data (DQ31-DQ8) are set to ’0’.
4. For M58LW064B, A1 = Don’t Care.
