Note: If you are using software such as LabVIEW, LabWindows, or NI-DAQ, you may need
to reconfigure your software to reflect any changes in jumper or switch settings.
Digital I/O Configuration
The AT-MIO-16 provides eight digital I/O lines. These lines are divided into two ports of four
lines each and are located at pins ADIO<3..0> and BDIO<3..0> on the I/O connector. You can
configure each port for input or output through software programming of a register on the
AT-MIO-16 board. Figure 2-5 shows a block diagram of the digital I/O circuitry.
