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 has 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 system must issue the reset command to return the device to reading array
data.
When a timeout occurs, the software must send a reset command to clear the timeout bit (DQ5) and to return
the EAC to read array mode. In this case, it is possible that the flash will continue to communicate busy for up
to 2 µs after the reset command is sent.
