Command interface
5.1.9
5.1.10
When the device exits the Auto Select mode, the device reverts to the Program Suspend
mode, and is ready for another valid operation. See Auto Select command sequence for
more information.
Program Resume command
After the Program Resume command is issued, the device reverts to programming. The
controller can determine the status of the program operation using the DQ7 or DQ6 status
bits, just as in the standard program operation. Refer to Section 6: Status register for details.
The system must issue a Program Resume command, to exit the Program Suspend mode
and to continue the programming operation.
Further issuing of the Resume command is ignored. Another Program Suspend command
can be written after the device has resumed programming.
Program command
The Program command can be used to program a value to one address in the memory array
at a time. The command requires four Bus Write operations, the final Write operation latches
the address and data in the internal state machine and starts the Program/Erase Controller.
Programming can be suspended and then resumed by issuing a Program Suspend
command and a Program Resume command, respectively (see Section 5.1.8: Program
Suspend command and Section 5.1.9: Program Resume command).
If the address falls in a protected block then the Program command is ignored, the data
remains unchanged. The Status Register is never read and no error condition is given.
After programming has started, Bus Read operations output the Status Register content.
See Section 6: Status register for more details. Typical program times are given in Table 15:
Program, Erase Times and Program, Erase Endurance cycles.
After the program operation has completed the memory will return to the Read mode, unless
an error has occurred. When an error occurs, Bus Read operations to the memory continue
to output the Status Register. A Read/Reset command must be issued to reset the error
condition and return to Read mode.
One of the Erase Commands must be used to set all the bits in a block or in the whole
memory from ’0’ to ’1’.
