Figure 6. Toggle Bit Algorithm
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified inter-
nal 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.
