| |
The arrays EEPROMRfACCKChnl1TxPwLevel, EEPROMRfAOfdmChnlTxPwLevel, EEPROMRfCCCKChnl1TxPwLevel, EEPROMRfCOfdmChnlTxPwLevel are initialized to zero and never changed. The three loops contain the same code. Only the index of the upper named arrays go from 0 to 2. Therefore the three loops can be combined to one loop from 0 to 13 which removes useless code.
