ListenEnd
Description
00
Modulestays in Rx mode. Listen mode stops and must be disabled.
01
Modulestays 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.
10
Modulestays in Rx mode until PayloadReady or Timeout interrupt occurs. Listen
mode then resumes in Idle state. FIFO content is lost at next Rx wakeup.
Upon detection of a valid packet, the sequencing is altered, as shown below:
