15 / 55 page  June 16, 2005 S29AL008D_00A3 S29AL008D 15 Da t a S h ee t Note for Tables and : Address range is A18:A-1 in byte mode and A18:A0 in word mode. See Word/Byte Configura- tion, on page 11. 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 (11.5 V to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Table 4, on page 16. In addition, when verifying sector protection, the sector ad- dress must appear on the appropriate highest order address bits (see Table 2, on page 14 and Table 3, on page 15). Table 4, on page 16 shows the remaining ad- dress 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 autose- lect command via the command register, as shown in Table 5, on page 25. This method does not require VID. See Command Definitions, on page 19 for details on using the autoselect mode. Table 3.
