I am interfacing s32k144 to a encoder with ABZ. AB is connected to FTM quad encoder,
which could config a number of filter length to AB signal. The Z signal is connected to
GPIO, and using ISR to clear FTM quad encoder counter. The problem is GPIO could
only enable or disable filter, while my situation seems to need a wider filter time.
If anyone encounter the same problem? How to achieve a wider filter for signal Z?
