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 X28LC512/513 memories that is frequently
updated. Toggle Bit Polling can also provide a method
for status checking in multiprocessor applications. The
timing diagram in Figure 3a illustrates the sequence of
events on the bus. The software flow diagram in Figure
3b illustrates a method for polling the Toggle Bit.
