    Custom Teensy3.2 - extra pins of the MKL04 bootloader chip.

    Hi all,

    I 'd wish to build my own teensy3.2 based on the MKL04Z32 chip as bootloader. Compared to the original teensy3.2 with MKL02 there are extra pins on the new chip. What should I do with those extra pins ? For example the analog pin Vref and others, do I have to connect them to either VSSA or VDDA as done on the MK20DX or do I have only to let then Non Connected ? I thank you guys by advance for your help, I do not know what the bootloader softaware is doing and what setup is achieved at boot-up sequence....

    Regards,

    Pap

    Leave all those extra pins unconnected.
