// As an interrupt may disappear while it is being fetched by the CPU
// (spurious interrupt caused by a delayed response from an MCU peripheral to
// an interrupt flag clear or interrupt disable instruction), check if there
// are remaining interrupt lines to process.
// If a spurious interrupt occurs, the status register (SR) contains an
// execution mode and interrupt level masks corresponding to a level 0
// 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.
// However, these spurious interrupts place the hardware in an unstable state
// and could give problems in other/future versions of the CPU, so the
// software has to be written so that they never occur. The only safe way of
// 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
// frame, with nothing more pushed onto the stack. The interrupt handler must
// manage the `rete' instruction, what can be done thanks to pure assembly,
// inline assembly or the `__attribute__((__interrupt__))' C function
