location is reached because DQ1=’1’, then the Write to Buffer Program command aborted. In both cases, the appropriate
reset command must be issued to return the device in Read mode: a Reset command if the operation failed, a Write to
Buffer Program Abort and Reset command if the operation aborted.
Table 9
Buffered Program Abort and Reset command
A Buffered Program Abort and Reset command must be issued to abort the Buffer Program
operation and reset the device in Read mode.
The buffer programming sequence can be aborted in the following ways:
The abort condition is indicated by DQ1 = 1, DQ7 = DQ7 (for the last address location
loaded), DQ6 = toggle, and DQ5 = 0 (all of which are Status Register bits). A Buffered
Program Abort and Reset command sequence must be written to reset the device for the
next operation. Note that the full 3-cycle Buffered Program Abort and Reset command
sequence is required when using Buffer Programming features in Unlock Bypass mode.

Load a value that is greater than the page buffer size during the number of
locations to program step in the Write to Buffer Program command.
Write to an address in a block different than the one specified during the write-
buffer-load command.
Write an address/data pair to a different write-buffer-page than the one selected by
the starting address during the program buffer data loading stage of the operation.
Write data other than the Confirm command after the specified number of data
load cycles.
