Usually a "spontaneous reboot" is the result of an exception happening
when already running in an interrupt or exception handler. Interrupts
and exceptions don't "nest" on the SuperH, so while the handler is
running there is just a mask bit in the status register that defers
interrupts and causes exceptions to reboot the system.
