Hello Emin, What is your application? I learned to read ppmsum using the pin change interrupt
that is only on pin 8. Outputs (pwm)are toggled directly from within the ISR. I used it for a head tracker, and a gimbal stabilizer with the imu v3. Only one 16 bit timer on the 328p and it does everything as time related with interupts.
