A :
* If you use AMICCOM RF IC without BOD function, you can reinitialize RF for a while to avoid some power supply noise interference to the RF IC power terminal and control terminal.

* If you use AMICCOM RF IC with BOD function:
      * Because the Ref. Code has made BOD judgment before TRX, it can avoid the situation that the power supply noise interference RF has been reset and the MCU does not know.

      * However, if there is an unknown reason and the RF IC control is abnormal, it is recommended to initial RF for a period of time.(To avoid some power noise interference to the RF IC control terminal but not to reset the RF IC power terminal.)
