Autoselect Mode  
The autoselect mode provides manufacturer and device  
identification, and sector protection verification, through  
identifier codes output on I/O7 - I/O0. 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 VID (11.5V to 12.5 V) on address pinA9.  
Address pins A6, A1, and AO must be as shown in  
Autoselect Codes (High Voltage Method) table. In  
addition, when verifying sector protection, the sector  
address must appear on the appropriate highest order  
address bits. Refer to the corresponding Sector Address  
Tables. The Command Definitions table shows the  
remaining address bits that are don't care. When all  
necessary bits have been set as required, the  
programming  
equipment  
may  
then  
read  
the  
corresponding identifier code on I/O7 - I/O0.To access the  
autoselect codes in-system, the host system can issue  
the autoselect command via the command register, as  
shown in the Command Definitions table. This method  
does not require VID. See "Command Definitions" for  
details on using the autoselect mode.
