4. The change of a UBC register value is executed in MA (memory access) stage. Therefore,
5. The branch instruction should not be executed as soon as PC trace register BRSR and BRDR
6. When PC breaks and TLB exceptions or errors occur in the same instruction. The priority is as
even if the break condition matches in the instruction fetch address following the instruction in
which the pre-execution break is specified as the break condition, no break occurs. In order to
know the timing UBC register is changed, read the last written register. Instructions after then
are valid for the newly written register value.
