THE TOGGLE BIT I/O

Figure 4. Toggle Bit Bus Sequence
Figure 5. Toggle Bit Software Flow
The Toggle Bit can eliminate the software housekeeping
chore of saving and fetching the last address and data
written to a device in order to implement
DATA
Polling.
This can be especially helpful in an array comprised of
multiple X28HC64 memories that is frequently updated.
Toggle Bit Polling can also provide a method for status
checking in multiprocessor applications. The timing
diagram in Figure 4 illustrates the sequence of events on
the bus. The software flow diagram in Figure 5 illustrates
a method for polling the Toggle Bit.
