Interrupts
Interrupts are generated by the GPIO and DAC pins, the internal timers, I
on various USB traffic conditions. All interrupts are maskable by the Global Interrupt Enable Register and the USB End Point Interrupt
Enable Register. Writing a ‘1’ to a bit position enables the interrupt associated with that bit position.

During a reset, the contents the Global Interrupt Enable Register
and USB End Point Interrupt Enable Register are cleared,
effectively, disabling all interrupts.
The interrupt controller contains a separate flip flop for each
interrupt. See
interrupt controller. When an interrupt is generated, it is first
registered as a pending interrupt. It stays pending until it is
serviced or a reset occurs. A pending interrupt only generates an
interrupt request if it is enabled by the corresponding bit in the
interrupt enable registers. The highest priority interrupt request
