433           what it does is restrict the levels of interrupt which are permitted
434           (a lower level indicates a higher priority) by lowering the value in
435           EPSW.IM from 7.  Any interrupt is permitted for which the level is
436           lower than EPSW.IM.
437 
438           Certain interrupts, such as DEBUGGER and virtual MN10300 on-chip
439           serial DMA interrupts are allowed to interrupt normal disabled
440           sections.
