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.  
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
