    Programming two interrupt sources with the same level and priority can result in undefined operation. The MPC564EVB hardware uses IRQ[0]/SGPIOC[0] to support the ABORT (Non Maskable Interrupt) function using the ABORT switch (SWITCH1 when BRK_EN jumper is inserted). This switch is used to force a non-maskable interrupt if the user's program execution should be aborted without issuing a RESET.
