are don’t care. When all necessary bits have been set as required, the programming equipment may then
read the corresponding identifier code on DQ7–DQ0.
To access the autoselect codes in-system, the host system can issue the autoselect command via the
command. This method does not require VID. See
autoselect mode. Autoselect mode can be used in either synchronous (Burst) mode or asynchronous (Non
Burst) mode.
The system must write the reset command to exit the autoselect mode and return to reading the array data.

The autoselect codes can also be accessed in-system via command sequences. See
The VersatileI/O (V

pin. The output voltage generated on the device is determined based on the V

These devices are capable of several modes of programming and or erase operations which are described in
detail in the following sections. However, prior to any programming and or erase operation, devices must be
set up appropriately as outlined in the configuration register
write operation, to write a command or command sequence (including programming data to the device and
erasing sectors of memory), the system must drive ADV# and CE# to V
address to the device, and drive WE# and CE# to V
programming data.
