3.18 Digital I/O connector

One of digital circuit's characteristics 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
ICPMB-8660
Digital Input and Output are control signals generally. You can
use these signals to control external devices that needs On/Off
circuit or TTL devices. The register address is 240H, 260H or
280H, which is selected in BIOS SETUP. You can read or
write data to the selected address to enable the function of
digital IO.
