Figure 2. DATA Polling Bus Sequence
Figure 3. DATA Polling Software Flow
DATA Polling can effectively halve the time for writing
to the X28HC256. The timing diagram in Figure 2 illus-
trates the sequence of events on the bus. The soft-
ware flow diagram in Figure 3 illustrates one method
of implementing the routine.
