CPU registers not displayed properly

scott gibson

I'm running CCS 4.1.1.00014 under XP using XDS510USB JTAG. When debugging code ACC A does not contain the correct value. If I watch reg A in the CPU registers watch box while calling an asmymbly function from C code it should contain the first paramater in the call. In this perticular case it's a long and should be 0x000E8000. But, ACC A in the watch window shows 0x00000E0000. If I “Open memory view at register address” the correct value is displayed ( 8000 000E). ACC B has the same issue. Is there a issue with the register view not displaying properly?

Scott,

The register view may be displaying something wrong, but what is the device you are using?

Cheers,

Rafael

320C54CST. I'm quite sure it's wrong. I tried "ld #1234h,a" after stepping through 6 nop's the value in A never changed. I can add a shift to the command such as "ld #1234h,4,a" and a then becomes 0x4000010000.
