The Spirit1 data sheet doesn't have a clear description of how to set the PA_POWER[X] registers for a desired power output level. I would like to set the PA for a 0dBm output - is there a table that relates the register setting to output power level?

I am using the SPSGRF-915 module. Other details: 902-928MHz band, GFSK modulation, 250kBaud, channel filter BW 564kHz, channel spacing 334.2kHz

Incrementing by 1 the PA register value will correspond about to half dB decrement of output power.

The following table would be the values to output power levels.
