Hi Lozenro,
As I am shaping up my TPC code and might comment as well :)
What about defining just:
#define AR_XmitPower 0x003f0000
#define AR_XmitPower_S 16
#define AR_XmitPower2 0x3f000000
#define AR_XmitPower2_S 24
.. as AR_XmitPower1 == AR_XmitPower2 == AR_XmitPower3 (with its shift as well)
and AR_XmitPower == AR_XmitPower0
Or do you have someting in mind to have the same value seperated ?
Greetings from Berlin
