0 Set (in FS and Rx) when the PLL is locked.
Cleared when it is not.
0 Set in Rx when the RssiValue exceeds RssiThreshold.
Cleared when leaving Rx.
0 Set when a timeout occurs (see TimeoutRxStart and
TimeoutRssiThresh)

0 Set when entering Intermediate mode.
Cleared when exiting Intermediate mode.
Please note that in Sleep mode a small delay can be
observed between AutoMode interrupt and the
corresponding enter/exit condition.
