Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector group 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 on address pin A9. Address pins A6,
A3, A2, A1, and A0 must be as shown in Table 7.12. In addition, when verifying sector protection, the sector
address must appear on the appropriate highest order address bits (see Table 7.4 on page 27 to Table 7.22
on page 45). Table 7.12 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 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 Table 10.2 on page 61 and Table 10.1 on page 62. This method does not
