Accelerated Program
The abort condition is indicated by DQ1 = 1, DQ7 = DATA# (for the last address location loaded), DQ6 =
toggle, and DQ5= 0. A Write-to-Buffer-Abort Reset command sequence must be written to reset the device
for the next operation.
Note that the Secured Silicon Sector, autoselect, and CFI functions are unavailable when a program
operation is in progress. This flash device is capable of handling multiple write buffer programming operations
on the same write buffer address range without intervening erases. For applications requiring incremental bit
programming, a modified programming method is required; please contact your local Spansion
representative. Any bit in a write buffer address range cannot be programmed from 0 back to a 1.
Attempting to do so may cause the device to set DQ5=1, of cause the DQ7 and DQ6 status bits to indicate
the operation was successful. However, a succeeding read shows that the data is still 0. Only erase
operations can convert a 0 to a 1.
The device offers accelerated program operations through the WP#/ACC or ACC pin depending on the
particular product. When the system asserts V

internal pull-up; when unconnected, WP# is at V
