9 / 36 page Am29F100 9 Table 2. Sector Addresses Tables (Am29F100T) Table 3. Sector Addresses Tables (Am29F100B) Autoselect Mode 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 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 (11.5 V to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Autoselect Codes (High Voltage Method) table. In ad- dition, when verifying sector protection, the sector ad- dress must appear on the appropriate highest order address bits. Refer to the corresponding Sector Ad- dress 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 program- ming 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 the Command Defini- tions table. This method does not require VID. See “Command Definitions” for details on using the autose- lect mode. Table 4.
