Appendix B: Digital I/O
One characteristic of digital circuit is its fast response to high or low signal. This kind of response is
highly needed for harsh and critical industrial operating environment. That’s why we design 4-bit
digital inputs and 4-bit digital outputs on the MOTHERBOARD.
Digital Input and Output, generally, are control signals. You can use these signals to control external
devices that needs On/Off circuit or TTL devices. You can read or write data to the selected address
to enable the function of digital IO.
