During the unlock bypass mode, only the Unlock
Bypass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset
command sequence. The first cycle must contain the
data 90h; the second cycle the data 00h. Addresses
are don’t cares. The device then returns to reading
array data.
The device offers accelerated program operations
through the WP#/ACC pin. This function is intended
only to speed in-system programming of the device
during system production. When the system asserts
V
HH
on the WP#/ACC pin, the device automatically
enters 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 any operation
other than accelerated programming, or device
damage may result. In addition, the WP#/ACC pin must
not be left floating or unconnected; inconsistent
behavior of the device may result.
Figure 3
illustrates the algorithm for the program oper-
ation. See
“Erase/Program Operations” on page 40
for
parameters, and
