The PCM-VDX-2-512 Digital I/O consists of sixteen dedicated programmable I/O pins consisting of two individual 8-bit
ports. Each port can be confugred as GPIO or Pulse Width Modulation (PWM) outputs.
All GPIO pins are independent and can be configured as inputs or outputs. When configured as outputs, pins have 8 mA
drive capability and are unterminated. When configured as inputs, pins are pulled-high with a 75k Ω resistance. Each
input pin also supports interrupt triggers.
All PWM pins are independent and can be configured to output a continuous frequency or a fixed number of pulses. The
frequency is selected by programming high and low pulse count values. An interrupt can be used to indicate when a
pulse count has completed.
The features are configured and controlled utilizing PCI configuration and I/O access instructions.
