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 manages 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 V
Any invalid combination of commands are ignored.
