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  
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.  
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
