INT1_SEL
Compounded interrupt, any one of the interrupts below is valid,
000000
INT_MIX will be valid.
Interrupt for antenna lock being accomplished after antenna
000001
diversity function running.
000010 Interrupt for RSSI and/or PJD being valid.
000011 Interrupt indicating successful receipt of Preamble.
000100 Interrupt indicating successful receipt of Sync Word.
000101 Interrupt indicating successful receipt of Addr.
000110 Interrupt indicating successful receipt and CRC check being passed.
000111 Interrupt indicating receipt of an entire and correct packet.
Indicates that the current data packet has been received with the
001000
occurring of one of the 4 cases below.
1. A complete and correct packet is received.
2. Manchester decoding error occurs and the decoding circuit
restarts automatically.
3. NODE ID receiving error occurs and the decoding circuit
restarts automatically.
4. A signal conflict is found and the decoding circuit does not
restart automatically but waits for the MCU to process.
001001 Interrupt indicating SLEEP timer timeout.
001010 Interrupt indicating RX timer timeout.
001011 Interrupt indicating RX FIFO being empty.
Interrupt indicating the unread content of RX FIFO exceeding FIFO
001100
TH.
001101 Interrupt indicating RX FIFO being full
001110 Interrupt generated every time a BYTE is written into RX FIFO, i.e.,
it is a pulse.
001111 Interrupt indicating RX FIFO being overflow
010000 Interrupt indicating TX completion.
010001 Interrupt indicating TX FIFO not being empty.
Interrupt indicating the unread content of TX FIFO exceeding FIFO
010010
TH.

010100 Interrupt indicating that the current state is READY.
010101 Interrupt indicating that the current state is RFS or TFS.
010110 Interrupt indicating that the current state is RX.
010111 Interrupt indicating that the current state is TX.
Interrupt indicating that low voltage detection being active (VDD is
011000
lower than the set TH).
