After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6
toggles for approximately 100 µs, then returns to reading array data. If not all selected sectors
are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the
selected sectors that are protected.
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 tog-
gling. However, the system must also use DQ2 to determine which sectors are erasing or erase-
suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling).
If a program address falls within a protected sector, DQ6 toggles for approximately 1 µs 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 Embed-
ded Program algorithm is complete.
Table 36
shows the outputs for Toggle Bit I on DQ6.
Figure 8
shows the toggle bit algorithm.
Figure 20
shows the toggle bit timing diagrams.
Figure 21
shows the differences between DQ2
and DQ6 in graphical form. Also, see
DQ2: Toggle Bit
II.
