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 X28C64 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.
