The Toggle Bit I/O6

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 FT28C010 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.
