R/W Adjusts current TX LO buffer (input to PA). The value to
use in this field is given by the SmartRF^® Studio
software.
R0 Reserved
R/W Selects PA power setting. This value is an index to the
PATABLE, which can be programmed with up to 8
different PA settings. The PATABLE settings from index
‘0’ to the PA_POWER value are used for power ramp-
up/ramp-down at the start/end of transmission in all TX
modulation formats.

Frequency synthesizer calibration result register.
Fast frequency hopping without calibration for each hop can be
done by calibrating upfront for each frequency and saving the
resulting FSCAL3, FSCAL2 and FSCAL1 register values. Between
each frequency hop, calibration can be replaced by writing the
FSCAL3, FSCAL2 and FSCAL1 register values corresponding to
the next RF frequency.
