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 X28HC256 memories that is frequently up-
dated. 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.
