Toggle Bit Flag (DQ6)

Like the data polling flag, the toggle bit flag uses the toggle bit function to post that the
automatic algorithm is being executed or has terminated.
■
Automatic Write/Erase
Making successive read accesses while the automatic writing/erasing algorithm is being performed toggles
flash memory and makes it output 1 and then 0, in turn, regardless of the specified address. Making
successive read accesses when the automatic writing/erasing algorithm ends makes flash memory to stop
bit6 toggle and outputs the value of bit6 (DATA:6) corresponding to the value read from the specified
address. The toggle bit becomes effective after the last write cycle in each command sequence.
