The RF output frequency is calculated by the following:
For the direct output
For the RF_DIVIDE_BY_2 (R1_DB18) selected
In UART/SPI mode, the TxRxCLK pin is used to input the
Tx data. The Rx Data is available on the TxRxDATA pin.

FILTER_CAL_ COMPLETE in the MUXOUT map in
Figure 63 indicates when a coarse or coarse plus fine
IF filter calibration has finished. DIGITAL_
LOCK_DETECT indicates when the PLL has locked.
RSSI_READY indicates that the RSSI signal has settled
and an RSSI readback can be performed.
Tx_Rx gives the status of DB27 in this register, which
can be used to control an external Tx/Rx switch.
