What peripheral functions restricted when E10A-USB is used in SH7125?

Latest Updated:03/24/2009

Question:

What are the on-chip peripheral functions restricted when E10A-USB is used in SH7125?

Answer:

When E10A-USB is used, the function to show in the table below cannot be used because the function pins (H-UDI function pins) for E10A-USB of SH7125 is multiplexed with other function pins.

If E200F is combined with an evaluation chip unit and a user I/F board, pins are never occupied for the emulator use.
