Section 5 Interrupt Controller
5.7
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.
5.7.2
Figure 5.8 shows a block diagram of the address break.
5.7.3
If the CPU prefetches an address specified in BAR by setting ABRKCR and BAR, an address
break interrupt can be generated. This address break function generates an interrupt request to the
interrupt controller at prefetch, and determines the priority by the interrupt controller. When an
interrupt is accepted, an interrupt exception handling is activated after the current instruction has
been completed. Note that the interrupt mask control according to the I and UI bits in CCR of the
CPU is invalid to an address break interrupt.
