Autoselect
IL
The Autoselect mode allows the host system to access manufacturer and device identification, and verify
sector protection, through identifier codes output from the internal register (separate from the memory array)
on DQ15-DQ0. This mode is primarily intended to allow equipment to automatically match a device to be
programmed with its corresponding programming algorithm. When verifying sector protection, the sector
address must appear on the appropriate highest order address bits (see
bits are don't care. When all necessary bits have been set as required, the programming equipment can then
read the corresponding identifier code on DQ15-DQ0.
The Autoselect codes can also be accessed in-system through the command register. Note that if a Bank
Address (BA) on the four uppermost address bits is asserted during the third write cycle of the Autoselect
command, the host system can read Autoselect data from that bank and then immediately read array data
from the other bank, without exiting the Autoselect mode.

(See Note)
H = Logic High = V
SA = Sector Address
To access the Autoselect codes, the host system must issue the Autoselect command.
The Autoselect command sequence can be written to an address within a bank that is either in the read or
erase-suspend-read mode.
The Autoselect command cannot be written while the device is actively programming or erasing in the other
bank.
Autoselect does not support simultaneous operations or page modes.
The system must write the reset command to return to the read mode (or erase-suspend-read mode if the
bank was previously in Erase Suspend).
