Even though it's a different processor and I don't know all the 
differences, I've found the SH-2A software manual 
http://documentation.renesas.com/doc/products/mpumcu/rej09b0051_sh2a.pdf 
has a better explanation of exception handling than the SH-2 software 
manual, if that's what you're looking for.
