The PA uses this
setting.
Settings 0 to PA_POWER are
used during ramp-up at start of
transmission and ramp-down at
end of transmission, and for
ASK/OOK modulation.
Index into PATABLE(7:0)
e.g 6
PA_POWER[2:0]
in FREND0 register
The SmartRF® Studio software
should be used to obtain optimum
PATABLE settings for various
output powers.
