Let's say I'd like to mount a MK20 chip directly on a PCB and use one of its PWM outputs to stimulate a ADC OSC input to the tune of 12MHz. (the teensy can manage that just fine)
However, there is no PWM pin near the SPI bus where I'd like to go... however, I could route a signal from a PWM pin *via* another existing pin. That is, run the signal through an unused pin. Is this possible/legal, or will the 'via pin' cause some sort of interference no matter how it is set (i.e. as input, for example)?
Just wondering, it would make my life a lot easier if this 'via pin' could be set as high-Z...
