For the VERSION register, the low byte is the version of the IP, but the up= per byte is a number that the design group that made the part gives it any = time they make a change. So, since this IP was from a SH2A team, the number= ing might look different than what the SH4A or R-Car teams have used in the= past. > This SWAP register exists on R-Car as well. Out of curiosity, what is the > register value of 0xE804E0E4? 0xE804E0E4 =3D 0x0001 So...something is there! Chris
