Toggle Bit D6
When Programming operations are in progress, successive attempts to read D6 will
output complementary data. D6 will toggle following toggling of either RDF or CSF
when RDF is low. The operation is completed when two successive reads yield the
same output data. The next read will output the bit last programmed or a ‘1’ after
erasing. The toggle bit is valid only effective during P/E.C. operations, that is after the
fourth WRF pulse for programming or after the sixth WRF pulse for Erase. If the byte to
be programmed belongs to a protected sector the command will be ignored. If the
sectors selected for erasure are protected, D6 will toggle for about 100 μs and then
return back to Read. See Figure 3 for Toggle Bit flowchart and Figure 4 for Toggle Bit
waveforms.
