Command interface

All Bus Write operations to the memory are interpreted by the Command Interface.

Commands consist of one or more sequential Bus Write operations. An internal

Program/Erase Controller handles all timings and verifies the correct execution of the

program and erase commands. The Program/Erase Controller provides a Status Register

whose output may be read at any time to monitor the progress or the result of the operation.

The Command Interface is reset to read mode when power is first applied, when exiting from

Reset or whenever VDD is lower than VLKO. Command sequences must be followed exactly.

Any invalid combination of commands will be ignored.

Refer to Table 4: Command codes, Table 5: Standard commands, Table 6: Factory

commands, and Appendix D: Command interface state tables, for a summary of the

Command Interface.
