The chip enters Run Mode Self Polling after a successful fulfillment of a wake up
criterion in Self Polling Mode.
The following steps are performed automatically, depending on register settings

Depending on the interrupt masking, the host micro controller is alerted when

Run Mode Self Polling is left, when synchronization is lost and the Time Out Timer
(TOTIM) has elapsed, and when the mode is switched to SLEEP or Run Mode Slave by
the host microcontroller.
As long as the chip is in Run Mode Self Polling, incoming data frames, even without
additional wake up patterns, can be received and stored.
The data FIFO can be either initialized and cleared at
