Note that if a Write Buffer address location is loaded multiple times, the address/data pair
counter will be decremented for every data load operation. The host system must therefore
account for loading a write-buffer location more than once. The counter decrements for each
data load operation, not for each unique write-buffer-address location. Note also that if an
address location is loaded more than once into the buffer, the final data loaded for that ad-
dress will be programmed.
Once the specified number of write buffer locations have been loaded, the system must then
write the Program Buffer to Flash command at the sector address. Any other address and data
combination aborts the Write Buffer Programming operation.
The device then begins pro-
gramming. Data polling should be used while monitoring the last address location loaded into
the write buffer. DQ7, DQ6, DQ5, and DQ1 should be monitored to determine the device sta-
tus during Write Buffer Programming.
The write-buffer programming operation can be suspended using the standard program sus-
pend/resume commands. Upon successful completion of the Write Buffer Programming
operation, the device is ready to execute the next command.
