TMS320F28388D: Is there a way we can check the configured register changing in runtime

Part Number: TMS320F28388D

Hello Experts,

I have a query on the peripheral Registers. Is there a method available to check that the register configurations are changed or not changed during the runtime of the application in this controller.

Let's say I have configured ADC for 12-bit configuration and during runtime, due to some glitch it got changed to 16 bit. Is there any direct method available to validate this kind of scenario?

Thanks

Mohan

    The only hardware way I can think to do this is with an ERAD hardware watch point. I believe it's specifically doing data write bus monitoring though, so it's limited to catching unexpected CPU accesses. For other disturbances, you would need to do a read back of the register value in software.

    Thank you for your response.

    We had t register read back as the only option and hence wanted to know from the experts. we will go ahead with the register read back.

    Thank you
