3.5.16. Timeout Function
The SX1231 includes a Timeout function, which allows it to automatically shut-down the receiver after a receive sequence
and therefore save energy.
Timeout interrupt is generated TimeoutRxStart x 8 x Tbit after switching to RX mode if RssiThreshold flag does not raise
within this time frame
Timeout interrupt is generated TimeoutRssiThresh x 8 x Tbit after RssiThreshold flag has been raised.
