ATSAML10E16A interrupt vectors

The vector table at the start of flash (VTOR moves it): word 0 is the initial stack pointer, then the 6 core exceptions (numbered below 0 as CMSIS does) and the 45 peripheral interrupts, IRQ 0 up. Each entry is the 4-byte address of its handler, at 4 × (IRQn + 16). The NVIC enables each IRQ and sets its priority; in C a handler is a function with the name below, e.g. void SERCOM0_Handler(void), and NVIC_EnableIRQ(SERCOM0_IRQn) turns it on.
