The capacitive load should not be larger than 50 pF for all I/Os when using the default driver strength settings, refer
on page 205
. Generally, large load capacitances increase the overall current consumption.

Pins RFN and RFP require an AC coupling if the external parts (e.g. balun, antenna) have a DC path to ground.
Serial capacitances and capacitance of each pin to ground must be < 30 pF.
