unused

PllLock

Set (in FS and Rx) when the PLL is locked.

Cleared when it is not.

Rssi

rwc

Set in Rx when the RssiValue exceeds RssiThreshold.

Cleared when leaving Rx.

Timeout

Set when a timeout occurs (see TimeoutRxStart and

TimeoutRssiThresh)

Cleared when leaving Rx or FIFO is emptied.

AutoMode

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.
