Am29F400BB Bottom Boot Block Sector Address Table Note: Address range is A17:A-1 in byte mode and A17: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 Table 4. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits (see Tables 2 and 3). Table 4 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. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 5. This method does not require VID. See “Command Definitions” for details on using the autoselect mode.
