Toggle Bit Algorithm
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.
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time exceeded a specified internal
pulse count limit. Under these conditions DQ5 produces a “1.” This is a failure
condition that indicates the program 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 previously programmed to “0.”
