Figure 8. Toggle Bit Algorithm
DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular
sector is actively erasing (that is, the Embedded Erase algorithm is in progress),
or whether that sector is erase-suspended. Toggle Bit II is valid after the rising
edge of the final WE# pulse in the command sequence.

No t e :
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 subsections on DQ6 and DQ2 for more
information.
