Load a value that is greater than the page buffer
size during the Number of Locations to Program
step.
Write to an address in a sector different than the
one specified during the Write-Buffer-Load com-
mand.
Write an Address/Data pair to a different
write-buffer-page than the one selected by the
Starting Address during the write buffer data load-
ing stage of the operation.
Write data other than the Confirm Command after
the specified number of data load cycles.
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 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
HH
on the WP#/ACC pin, the device automatically en-
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
HH
for operations
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
CC
.
Figure 5 illustrates the algorithm for the program oper-
ation. Refer to the
Erase and Program Operations
table in the AC Characteristics section for parameters,
and Figure 17 for timing diagrams.
