CCS/TMS320F28377D: CCS debug window: GPIO SET/CLR via CLA

Part Number: TMS320F28377D

Tool/software: Code Composer Studio

Hi,

I am using CLA to control GPIO22/GPIO23. The code works OK. CLA code can take control of them in free run mode.

But I cannot change the GPIO22/23 directly in CCS debug with XDS100V3 even if I select CLA core first.

If I change back the owner to CPU(via GPACSEL3 config.), I can do such action easily. 

What is wrong with this?  Is it due to dubugger itself or something else? 

 Waiting for your help and thanks in advance.

    When you use the emulator, the emuulator writes occur via the C28x. So if you assign the master to the CLA, I do no think the debugger will be able to write to those registers. Only the CLA will be able too.
