I have tried several ways to read this value, but it seems there are some issues:
1. In IAR debug mode, we can choose to display register values, but TXCTRLL is not included inside.
2. choose to directly read the TXCTRLL value in local value box in debug mode, dose not work(I assume TXCTRLL is global)
3. made a function inside to directly read the TXCTRLL value, I can successfully read the value, but it seems that the TXCTRLL value reading dose not reflect the real Tx power
Anyone has experience on that?
Thanks
