Table 14. Query Structure Overview

Table 15. CFI - Query Address and Data Output in the x16/x32 organization

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.
