Sector erase timer (DQ3) Checks whether sector erase timer window is open. If DQ3 = 1, erase is in progress; no commands will be accepted. If DQ3 = 0, the device will accept sector erase commands. Check DQ3 before and after each sector erase command to verify that the command was accepted. Toggle bit 2 (DQ2) During sector erase, DQ2 toggles with OE or CE only during an attempt to read a sector being erased. During chip erase, DQ2 toggles with OE or CE for all addresses. If DQ5 = 1, DQ2 toggles only at sector addresses where failure occurred, and will not toggle at other sector addresses. Use DQ2 in conjunction with DQ6 to determine whether device is in auto erase or erase suspend mode.
