The RFIdle() function sets the transceiver and the RF stack into an IDLE state independent of the actual state of
the RF stack. It disables the transmit/receive mode and all the interrupts. It then reads the interrupt status registers
from the radio and clears the IT flags.
The RFTransmit() function starts packet transmission and ensures packets are sent successfully.
The RFReceive() function enables packet reception by enabling the receiver and setting up the relevant interrupts
prior to and reading the interrupt status registers.
The RFPacketReceived() function checks whether the packet is received or not. It reads the data packet from the
FIFO if all packet handlers and the CRC are correct.
