NOP instruction is executed at breakpoint address H'0312 and
next address, H'0314; fetch from address H'0316 starts after
end of exception handling.
MOV instruction is executed at breakpoint address H'0312,
NOP instruction at next address, H'0316, is not executed;
fetch from address H'0316 starts after end of exception handling.
NOP instruction at breakpoint address H'0312 is not executed;
fetch from address H'0312 starts after end of exception handling.
