Upon detection of a valid packet, the sequencing is altered, as shown below:
Listen mode can be disabled by writing ListenOn to 0.
4.3.4. Stopping Listen Mode
To abort Listen mode operation, the following procedure must be respected:
4.3.5. RC Timer Accuracy
All timings of the Listen Mode rely on the accuracy of the internal low-power RC oscillator. This oscillator is automatically
calibrated at the device power-up, and it is a user-transparent process.
For applications enduring large temperature variations, and for which the power supply is never removed, RC calibration
can be performed upon user request. RcCalStart in RegOsc1 can be used to trigger this calibration, and the flag
RcCalDone will be set automatically when the calibration is over.
