Figure 7. Toggle Bit Algorithm
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count
limit. Under these conditions DQ5 produces a 1. This is a failure condition that indicates the pro-
gram or erase cycle was not successfully completed.
The DQ5 failure condition may appear if the system tries to program a 1 to a location that is pre-
viously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this

Notes:
1. Read toggle bit twice to determine whether or not it
is toggling. See text.
2. Recheck toggle bit because it may stop toggling as
DQ5 changes to 1. See text.
