The exception handler is invoked when an exception occurs in the PPU. This handler logs the exception data and sets the firmware error bit in the Error Manager.

If an exception occurs before the boot PDI programming is complete, the PLM Error Manager updates the PMC MultiBoot register and triggers a system reset (SRST). However, if an exception occurs after the boot PDI programming is complete, then the PLM application runs in an infinite while loop.
