Hi all,

The Teensy3 pinout drawing shows a second copy of Serial1 signals and some SPI signals. I checked the MK20 datasheet and these are valid pin routing options. Is it possible to make use of them using the supplied libraries? For example, I would like to put SCK on pin D14.

Also, the SPI pinout shows 5 chip selects. Does the Teensy3 SPI library make use of them? If so, how? Or do I have to manually manipulate them as per the standard Arduino SPI library?
