22 / 69 page  20 S29AL032D S29AL032D_00_A3 June 13, 2005 Advan ce In form ati o n Autoselect Mode The autoselect mode provides manufacturer and device identification, and sector protection ver- ification, 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 correspond- ing 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 8. In addition, when ver- ifying sector protection, the sector address must appear on the appropriate highest order address bits (see Table 2 on page 14 and Table 4 on page 16). Table 8 shows the remaining address bits that are don’t care. When all necessary bits have been set as required, the programming equip- ment 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 17 on page 38. This method does not require VID. See “Command Definitions” for details on using the autoselect mode. Table 8. S29AL032D Autoselect Codes (High Voltage Method) L = Logic Low = VIL, H = Logic High = VIH, SA = Sector Address, X = Don’t care. Note: The autoselect codes may also be accessed in-system via command sequences. See Table 17 on page 38. Sector Protection/Unprotection The hardware sector protection feature disables both program and erase operations in any sector. The hardware sector unprotection feature re-enables both program and erase operations in pre- viously protected sectors.
