Section 30 User Break Controller (UBC)
30.4 User Break Debugging Support Function
By using the user break debugging support function, the branch destination address can be
modified when the CPU accepts the user break request. Specifically, setting the UBDE bit of
break control register CBCR to 1 allows branching to the address indicated by DBR instead of
branching to the address indicated by the [VBR + offset]. Figure 30.2 shows the flowchart of the
user break debugging support function.
