Table 7. In addition, when verifying sector protection,  
Autoselect Mode  
the sector address must appear on the appropriate  
highest order address bits (see Tables 3–6). Table 7  
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 corre-  
sponding identifier code on DQ7–DQ0.  
The autoselect mode provides manufacturer and de-  
vice identification, and sector protection verification,  
through identifier codes output on DQ7–DQ0. This  
mode is primarily intended for programming equip-  
ment to automatically match a device to be pro-  
grammed with its corresponding programming  
algorithm. However, the autoselect codes can also be  
accessed in-system through the command register.  
To access the autoselect codes in-system, the host  
system can issue the autoselect command via the  
command register, as shown in Table 14. This method  
does not require VID. Refer to the Autoselect Com-  
mand Sequence section for more information.  
When using programming equipment, the autoselect  
mode requires VID (8.5 V to 12.5 V) on address pin A9.  
Address pins A6, A1, and A0 must be as shown in  
Table 7. Autoselect Codes, (High Voltage Method)
