The address break simplifies on-board program debugging. It requests an address break interrupt
when the set break condition is satisfied. The interrupt request is not affected by the I bit of CCR.
Break conditions that can be set include instruction execution at a specific address and a
combination of access and data at a specific address. With the address break function, the
execution start point of a program containing a bug is detected and execution is branched to the
correcting program. Figure 4.1 shows a block diagram of the address break.
