Appendix
E.
The SH7785 has the read-only registers which show the version of a processor core, and the
version of a product. By using the value of these registers, it becomes possible to be able to
distinguish the version and product of a processor from software, and to realize the scalability of
the high system. Since the values of the version registers differ for every product, please refer to
the hardware manual or contact Renesas Technology Corp.
Note: The bit 7 to bit 0 of PVR register and the bit 3 to bit 0 of PRR register should be masked
