During unlock and command cycles, when lower address bits are 555 or 2AAh as shown in table, address bits higher than A11 (except where BA is required) and data bits higher than DQ7 are don’t cares. 5. No unlock or command cycles required when bank is reading array data. 6. The Reset command is required to return to reading array (or to erase-suspend-read mode if previously in Erase Suspend) when bank is in autoselect mode, or if DQ5 goes high (while bank is providing status information). 7. Fourth cycle of autoselect command sequence is a read cycle. System must provide bank address to obtain manufacturer ID or device ID information. See “Autoselect Command Sequence” on page 46 for more information. 8. The data is DQ6=1 for factory and customer locked and DQ7=1 for factory locked. 9.
