Toggle Bit Algorithm
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
subsections on DQ6 and DQ2 for more information.
10.14 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.
DQ2 toggles when the system reads at addresses within those sectors that were selected for erasure. (The
system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the
sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is
actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus,
both status bits are required for sector and mode information. Refer to
Table 10.5 on page 60
to compare
outputs for DQ2 and DQ6.
