//  void halRfSendPacket(BYTE *txBuffer, UINT8 size)
//
//  DESCRIPTION:
//      This function can be used to transmit a packet with packet length up to 63 bytes.
//      To use this function, GD00 must be configured to be asserted when sync word is sent and 
//      de-asserted at the end of the packet => halSpiWriteReg(CCxxx0_IOCFG0, 0x06);
//      The function implements polling of GDO0. First it waits for GD00 to be set and then it waits
//      for it to be cleared.  
//      
//  ARGUMENTS:
//      BYTE *txBuffer
//          Pointer to a buffer containing the data that are going to be transmitted
//
//      UINT8 size
//          The size of the txBuffer
//-------------------------------------------------------------------------------------------------------
