Appendix4.6 Processing of the index register

The index register of the A2USHCPU-S1, A2USCPU(S1) and A2ASCPU(S1/S30) is
rewritten to the value prior to the execution of the interrupt program when the processing is
transferred to the main or sequence program even if the value was updated by the
interrupt program.
