8.8  
Autoselect Mode  
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 VID on address pin A9. Address pins A6,  
A3, A2, A1, and A0 must be as shown in Table 8.9 on page 29. In addition, when verifying sector protection,  
the sector address must appear on the appropriate highest order address bits (see Table 8.2 - Table 8.8).  
Table 8.9 shows the remaining address bits that are don’t care. When all necessary bits are set as required,  
the programming equipment may then read the corresponding identifier code on DQ7–DQ0.  
To access the autoselect codes in-system, the host system can issue the autoselect command via the  
command register, as shown in Table 10.1 on page 51 and Table 10.3 on page 53. This method does not  
require VID. Refer to the Autoselect Command Sequence section for more information.
