Number of Slices Enabled in the PA Driver.
+-This parameter determines the output current drive of the PA. The values entered
into this register come from the Power Amplifier Module API.
PA Level Bias.
This parameter determines the bias current per slice of the PA. The values entered
into this register come from the Power Amplifier Module API.
PA Variable Capacitance.
Linear control of the output capacitance of the PA. Range: 2.4–-12.5 pF (not exact
values). The resonance frequency and impedance matching between the PA output
and the connected antenna can be tuned by changing this value. This register is set
by the Power Amplifier Module API.
