3.3 Functional description
This section describes the different operating modes of the RF transceiver and the parameters used to
control it.
The RF transceiver module has a built-in state machine that controls the transitions between the different
operating modes. The state machine is controlled by SFR register RFCON and RF transceiver register
CONFIG, see section 3.5 for details.
3.3.1 Operational Modes
You can configure the RF transceiver to power down, standby, RX and TX mode. This section describes
these modes in detail.
3.3.1.1 State diagram
The state diagram (Figure 6.) shows the operating modes of the RF transceiver and how they function. At
the end of the reset sequence the RF transceiver enters Power Down mode. When the RF transceiver
enters Power Down mode the MCU can still control the module through the SPI and the rfcsn bit in the
RFCON register.
There are three types of distinct states highlighted in the state diagram:
• Recommended operating mode: is a recommended state used during normal operation.
• Possible operating mode: is a possible operating state, but is not used during normal operation.
• Transition state: is a time limited state used during start up of the oscillator and settling of the PLL.
