Command interface
6.1.10
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 6.1.8: Program
and
Suspend command
Section 6.1.9: 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
and
Figure 17: Write enable controlled program waveforms (8-bit mode)
Figure 18: Write
for more details. Typical program times
enable controlled program waveforms (16-bit mode)
are given in
Table 17: 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’.
The program operation is aborted by performing a reset or powering-down the device. In
this case data integrity cannot be ensured, and it is recommended to reprogram the word or
byte aborted.
