5. Changing the SR register value and accepting exception
A. When the MD or BL bit in the SR register is changed by the LDC instruction, the
acceptance of the exception is determined by the changed SR value, starting from the next
instruction.* In the completion type exception, an exception is accepted after the next
instruction has been executed. However, an interrupt of completion type exception is
accepted before the next instruction is executed.
Note: * When the LDC instruction for SR is executed, following instructions are fetched again
and the instruction fetch exception is evaluated again by the changed SR.
