I know. It is just that I haven't seen this one "in the wild" so far.

The SDHI IP came from the SH7269 (SH-2A device).
For the VERSION register, the low byte is the version of the IP, but the upper
byte is a

Nice. Could you ping me when this comes out?

Okay, this is a version I have not seen before.

In the current hardware manual on renesas.com, the SHDI section is not included.
However, for version 3.0 that will be posted shortly, it will start to include
the SDHI section.

For the r7s72100 SOC, the DATA_PORT register was changed to 32-bits wide.
Therefore a new flag has been created that will allow 32-bit reads/writes
to the DATA_PORT register instead of 16-bit (because 16-bits accesses are
not supported).
