10 / 39 page 10 Am29F200A P R E L I M I NARY Table 2. Am29F200T Top Boot Block Sector Address Table Table 3. Am29F200B Bottom Boot Block Sector Address Table Note for Tables 2 and 3: Address range is A16:A-1 in byte mode and A16:A0 in word mode. See “Word/Byte Configuration” section for more information. 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 “Au- toselect Command Sequence” for details on using the autoselect mode.
