TMS320F280049: How to read Active register value when shadow mode is enabled.

Hi Experts,

Please let me know how to read the Active register value when the shadow mode is enabled.
"The memory address of the active register and the shadow register is identical."
There used to be a CMPAM mirror register on F2806x.
However, F28004x does not have the mirror register to read the Active register value.

Thank you for your kind support.
Best regards,
Hitoshi Sugawara

Hi Hitoshi,

I apologize for the delay, unfortunately, there is no way to read the active register content when the shadow mode is enabled. You are correct that the older devices had this capability through the mirror register but on the newer devices this was removed.

Best Regards,

Hi Marlyn,

Thank you for your clarification.
Will ask the customer if they could read the Active register value with disabling the shadow mode.

Best regards,
Hitoshi
