this field is given by the SmartRF
R0
0 (000)
R/W
Selects PA power setting. This value is an index to the
PATABLE. In OOK mode, this selects the PATABLE index to
use when transmitting a ‘1’. PATABLE index zero is used in
OOK when transmitting a ‘0’.

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.
