Notes 1: Vector addresses contain interrupt jump destination addresses.
2: USB function interrupt occurs owing to an interrupt request of the endpoint x (x = 0 to 2) IN, endpoint x (x = 1, 2) OUT, USB reset or suspend/resume.
3: Reset functions in the same way as an interrupt with the highest priority.
