Write to Buffer and Program command
The Write to Buffer and Program command makes use of the device’s double word (32 bit)
Write Buffer to speed up programming.
Up to eight double words can be loaded into the Write Buffer and programmed into the
memory.
Four successive steps are required to issue the command.
1.
2.
3.
4.
If any address is outside the block boundaries or if the correct sequence is not followed,
Status Register bits 4 and 5 are set to ‘1’ and the operation will abort without affecting the
data in the memory array. A protected block must be unprotected using the Blocks
Unprotect command.
During a Write to Buffer and Program operation the memory will only accept the Read
Status Register and the Program/Erase Suspend commands. All other commands are
ignored. If PEN is at V
operation aborts and the Status Register PEN bit (bit 3) is set to '1'.
The Status Register should be cleared before re-issuing the command.
One Bus Write operation is required to set up the Write to Buffer and Program
command. Any Bus Read operations will start to output the Status Register after the 1st
cycle.
Use one Bus Write operation to write the selected memory block address (any address
in the block where the values will be programmed can be used) along with the value N
on the Data inputs/outputs, where N+1 is the number of words to be programmed. The
maximum value of N+1 is 8 words.
Use N+1 Bus Write operations to load the address and data for each word into the write
buffer. The address must be between Start address and Start address plus N, where
Start address is the first word address.
Finally, use one Bus Write operation to issue the final cycle to confirm the command
and start the Program operation.
