+ * \brief AVR32 UC3 ISP trampoline.
+ *
+ * In order to be able to program a project with both BatchISP and JTAGICE mkII
+ * without having to take the general-purpose fuses into consideration, add this
+ * file to the project and change the program entry point to _trampoline.
+ *
+ * The pre-programmed ISP will be erased if JTAGICE mkII is used.
+ *
+ * - Compiler:           GNU GCC for AVR32
+ * - Supported devices:  All AVR32UC devices can be used.

+  // 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
