13 / 50 page ![]() A29DL32x Series PRELIMINARY (May, 2005, Version 0.0) 12 AMIC Technology, Corp. Autoselect Mode The autoselect mode provides manufacturer and device identification, and sector protection verification, through identifier codes output on I/O7 - I/O0. 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 (8.5V to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Table 5. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits. (see Table 3-4). Table 5 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 corresponding identifier code on I/O7 - I/O0. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 12. This method does not require VID. Refer to the Autoselect Command Sequence section for more information. Table 5.
