The write-buffer programming operation can be sus-
pended using the standard program suspend/resume
commands. Upon successful completion of the Write
Buffer Programming operation, the device is ready to
execute the next command.
The Write Buffer Programming Sequence can be
aborted in the following ways:
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

step.
Write to an address in a sector different than the
one specified during the Write-Buffer-Load com-
mand.
Write

Starting Address during the write buffer data load-
ing stage of the operation.

command sequence must be written to reset the de-
vice for the next operation. Note that the full 3-cycle
Write-to-Buffer-Abort Reset command sequence is re-
quired when using Write-Buffer-Programming features
in Unlock Bypass mode.
Accelerated Program
The device offers accelerated program operations
through the WP#/ACC pin. When the system asserts
V
ters the Unlock Bypass mode. The system may then
write the two-cycle Unlock Bypass program command
sequence. The device uses the higher voltage on the
WP#/ACC pin to accelerate the operation. Note that
the WP#/ACC pin must not be at V
other than accelerated programming, or device dam-
age may result. In addition, no external pullup is nec-
essary since the WP#/ACC pin has internal pullup to
V

ation. Refer to the
