The autoselect mode provides manufacturer and device identification, and sector
protection verification, through identifier codes output on DQ7–DQ0. This mode
is primarily intended for programming equipment to automatically match a device
to be programmed with its corresponding programming algorithm. However, the
autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires V
dress pin A9. Address pins must be as shown in
verifying sector protection, the sector address must appear on the appropriate
highest order address bits.
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. How-
ever, the autoselect codes can also be accessed in-system through the command
register, for instances when the device is erased or programmed in a system with-
out access to high voltage on the A9 pin. The command sequence is illustrated in
Table
during the third write cycle of the autoselect command, the host system can read
autoselect data that bank and then immediately read array data from the other
bank, without exiting the autoselect mode.
T o access the autoselect codes in-system, the host system can issue the autose-
lect command via the command register, as shown in
