5.7.1
This LSI can determine the specific address prefetch by the CPU to generate an address break
interrupt by setting ABRKCR and BAR. If an address break interrupt is generated, the address
break interrupt exception handling is performed.
With this function, the execution start point of a program containing a bug is detected and
execution is branched to the correcting program.
