SH4 (SH7750) UDI - SDSR register

Hello,

Sorry to write in English, but my Japanese is very bad.

I hope somebody can help me with my problem.

I connected my CodeScape (DASH Classic) probe to my PCB with SH4(SH7750) - The board is from a Dreamcast.

When I start the CodeScape application I receive this message:

"Target not recognized: SDSR = 0x12345678".

SDSR for UDI does not exists in SH7750 Manual.

How can I fix this problem?.

ありがとう ございます!。
