//
//  DESCRIPTION:
//      This function can be used to receive a packet of variable packet length (first byte in the packet
//      must be the length byte). The packet length should not exceed the RX FIFO size.
//      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);
//      Also, APPEND_STATUS in the PKTCTRL1 register must be enabled.
//      The function implements polling of GDO0. First it waits for GD00 to be set and then it waits
//      for it to be cleared.
//      After the GDO0 pin has been de-asserted, the RXBYTES register is read to make sure that there
//      are bytes in the FIFO. This is because the GDO signal will indicate sync received even if the
//      FIFO is flushed due to address filtering, CRC filtering, or packet length filtering.
//
//  ARGUMENTS:
//      BYTE *rxBuffer
//          Pointer to the buffer where the incoming data should be stored
//      UINT8 *length
//          Pointer to a variable containing the size of the buffer where the incoming data should be
//          stored. After this function returns, that variable holds the packet length.
//
//  RETURN VALUE:
//      Bool
//          TRUE:   CRC OK
//          FALSE:  CRC NOT OK
