Note: * If an LDC instruction is executed for the SR, the following instructions are re-fetched
the SSR is restored into the SR. An acceptance of an exception related to instruction access is
determined according to the SR before restore. An acceptance of other exceptions is
determined by the SR after restore, processing mode, and BL bit value. A processing-
completion type exception is accepted before an instruction at the RTE branch destination
address is executed. However, note that the correct operation cannot be guaranteed if a re-
execution type exception occurs.
