|The features panel lists features in their priority order, along with the current pin allocation status. In the image on the left, servo PWM input requires specific pins and therefore has priority over digital input. Pins 9 and 10 are shown in green to indicate they are good to go for servo PWM. Likewise the digital input using pin 8 has no conflict, also green.
Pin 9 has also been selected for use as a digital input but conflicts with a higher priority feature, so is shown in red along with the name of the other feature it conflicts with.
There are no conflicts for pin 10, but since it has already been allocated by a higher priority feature, is shown in orange as a reminder/warning in every feature where it will not be available.
