Thank you for an opinion.
I confirmed whether other Solution Engine worked.
Solution Engine of SH3(09A) worked.
but, it will work only with my boot environment.
there was still a lot of problems.

OK. I understand. Probably, I thought so. 
I will revise this.

According to the manual of MRSHPC, there was resize to PCMCIA bus.
On this account byte/word space every 256KByte thinks that 
there is not semantics.
Then, I have decided to do every access to real-word space.
Is this wrong? (However, this is the cause of confusion.)
