4.4 Programmable Function I/O
The PCI-69222/PCI-69223 supports a powerful programmable
function I/O provided by an FPGA chip. These function I/O can be
configured as TTL DI/DO or 32-bit timer/counters. In addition, the
timer/counter supports a variety of modes, including general
purpose timer/counter, PWM output, or encoder input for simple
motion control. These signals are single-ended and 5V TTL-
compliant.
TTL DI/DO
Programmable function I/O can be used as static TTL-compliant 8-
CH digital input and 4-CH digital output. You can read/write these
I/O lines by software polling. Its sample and update rate is fully
controlled by software timing.
