The PCI-1712/1712L supports 16 digital I/O channels. These I/O
channels are divided into two bytes: specifically a low byte, DIO0 to
DIO7; and a high byte, DIO8 to DIO15. You can use each byte as either
an input port or an output port by configuration register; and all eight
channels of the byte have the same configuration. For detailed
information, please refer to Appendix D.16 Digital I/O configuration
registers.
In digital I/O function, you do not need to specify the clock source or
trigger source. When you want to output data, you just need to write
the data to the digital output channel through software. In the same
way, you can use software to read the data from digital input channel.
The default configuration after power on, hardware reset or software
reset is to set all the digital I/O channels to logic-low so that users
need not worry about damaging external devices during system start
up or reset.
