13.2. Output Power Programming

The RF output power from the device is

programmable by the 8-bit PA_POWER

the output power and total current

consumption

function

the

PA_POWER register setting. It is more

efficient in terms of current consumption to

use either the lower or upper 4-bits in the

the figures. However, the output power

can be controlled in finer steps using all

the available bits in the PA_POWER
