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 Table 2 on page 9). Table 4 shows the remaining address bits that are don’t care. When all necessary bits are 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 on page 17. This method does not require VID. See “Command Def- initions” on page 13 for details on using the autoselect mode. May 5, 2006 21557F4 Am29LV001B 9 11 Page
