The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-
suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6
toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must
also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use
If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program
command sequence is written, then returns to reading array data.
DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program
algorithm is complete.
Table 16.1 on page 70 shows the outputs for Toggle Bit I on DQ6. Figure 16.2 on page 68 shows the toggle
bit algorithm. Figure 20.11 on page 82 in shows the toggle bit timing diagrams. Figure 20.12 on page 82
shows the differences between DQ2 and DQ6 in graphical form. See also the DQ2: Toggle Bit II on page 69.

Note:
The system should recheck the toggle bit even if DQ5 = “1” because the toggle bit may stop toggling as DQ5 changes to “1.” See the DQ6:
