PWM timers in Micro controller trigger interrupt and write value from shadow
registers periodically. With this method there may be jitter from higher
priority interrupts, maybe a similar technique could be used?

"The output is buffered, which allows for stable operation of the motors.
The readout of the input states is performed after each input change,
not more frequently than every 20ms.

None at all. You could even hook a Pico PPMC to the parport and run it
alongside the 7i92.

It uses special mechanisms that allow stable and reliable work even with
a computer that has high delay values (Jitter) up
