DATASHEET
Notes - the accuracy of the typical timings given in Table 13 will depend in the RC oscillator calibration
- RC oscillator calibration is required, and must be performed at power up. See section 4.3.4 for details
4.3.2. Criteria
The criteria taken for detecting a wanted signal and hence deciding to maintain the receiver on is defined by ListenCriteria
in RegListen1.

Description
Chip stays in Rx mode. Listen mode stops and must be disabled.
Chip stays in Rx mode until PayloadReady or Timeout interrupt occurs. It then goes to the
mode defined by Mode. Listen mode stops and must be disabled.
Chip stays in Rx mode until PayloadReady or Timeout interrupt occurs. Listen mode then
resumes in Idle state. FIFO content is lost at next Rx wakeup.
