/*For some reason in our board, which I've been explained but I'm not capable of explaining it again, including LED1 and LED4 being part of usb serial,
we can't use plain pinMode and digitalWrite on those pins (at least the output ones, for what I've tried so far), so we gotta use registers and modify them manually
While this is a bit of a PITA, runs faster on the the uC
Also using Arduino Micro bootloader, seems to work fine
If Arduino Micro bl doesn't appear to work right, try the Sparkfun ProMicro ones
