Packet Receiving.
When pkrx = 1 the radio is currently receiving a valid packet.
Valid Packet Received.
When a pkvalid = 1 a valid packet has been received by the receiver. (Same bit
as in register 03, but reading it does not reset the IRQ)
CRC Error.
When crcerror = 1 a Cyclic Redundancy Check error has been detected. (Same
bit as in register 03, but reading it does not reset the IRQ)
Packet Transmitting.
When pktx = 1 the radio is currently transmitting a packet.
