PIN13 (PA02) analogWrite doesn't work as it should (D11C14A)

[zolianek]

Hi! I am using non-sdcard bootloader on SAMD11C14A and while trying to do a fading sketch with pin13 it does behave very strange. No matter what I do I can't make it behave as it should. I discovered that it skips any value from 1 to ~190 so to get a proper fading I have to set values between 190 and 255 as the LED does not light up with any value between 1 and 190.
