Digital I/O Signals
The DT3153 board provides four digital I/O lines (pins 2, 3, 4, and 12)
on connector J1. These digital lines are simple register-driven,
TTL-level inputs and outputs that you can use for any purpose, such
as controlling or actuating external devices. A bit value of 0 identifies
a low TTL level; a bit value of 1 identifies a high TTL level.
You can configure, write to, and read from the digital I/O lines using
software.
