I am now moving towards designing a PCB using the MK22FN512VLH12 MCU and I can't seem to find in the data sheet or manual the requirements of the MCU to work standalone on the PCB. Where do I need external resistors, capacitors, crystals, etc... I am also planning to use SWD for programming, and I suspect I will need a pull-up resistor somewhere, but I can't find this information in the specs.
