-  // If a spurious interrupt occurs, the status register (SR) contains an

-  // interrupt, whatever the interrupt priority level causing the spurious
-  // event. This behavior has been chosen because a spurious interrupt has not
-  // to be a priority one and because it may not cause any trouble to other
-  // interrupts.

-  // and could give problems in other/future versions of the CPU, so the

-  // achieving this is to always clear or disable peripheral interrupts with the
-  // following sequence:
-  // 1: Mask the interrupt in the CPU by setting GM (or IxM) in SR.
-  // 2: Perform the bus access to the peripheral register that clears or
-  //    disables the interrupt.
-  // 3: Wait until the interrupt has actually been cleared or disabled by the
-  //    peripheral. This is usually performed by reading from a register in the
-  //    same peripheral (it DOES NOT have to be the same register that was
-  //    accessed in step 2, but it MUST be in the same peripheral), what takes
-  //    bus system latencies into account, but peripheral internal latencies
-  //    (generally 0 cycle) also have to be considered.
-  // 4: Unmask the interrupt in the CPU by clearing GM (or IxM) in SR.
-  // Note that steps 1 and 4 are useless inside interrupt handlers as the
-  // corresponding interrupt level is automatically masked by IxM (unless IxM is
-  // explicitly cleared by the software).
-  //
-  // Get the right IRQ handler.
-  //
-  // If several interrupt lines are active in the group, the interrupt line with
-  // the highest number is selected. This is to be coherent with the
-  // prioritization of interrupt groups performed by the hardware interrupt
-  // controller.
-  //
-  // If no handler has been registered for the pending interrupt,
-  // _unhandled_interrupt will be selected thanks to the initialization of
-  // _int_line_handler_table_x by INTC_init_interrupts.

-  // exception.S will provide the interrupt handler with a clean interrupt stack
