In the datasheet it is said that the IMXRT1060 has 3 FLEXIO units. But when I try to access FLEXIO1 and FLEXIO2 my program crashes. Access to FLEXIO3 works. In the PWM unit the datasheet says that a unit may have an "NanoEdge placer block". Where can I get the info wich FLEXPWM unit has it and wich not?
