Number of Slices Enabled in the PA Driver.
This parameter determines the output current drive of the PA. Programming this
register directly is not recommended. Use the vPa_Setup() API function instead.
PA Level Bias.
This parameter determines the bias current per slice of the PA. Programming this
register directly is not recommended. Use the vPa_Setup() API function instead.
PA Variable Capacitance.
9-bit linear control value of the output capacitance of the PA. Accessed as 2 bytes
(word) in big-endian fashion. Upper bits [15:9] are read as 0. 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.
