Note: PG4/TOSC1 and PG3/TOSC2 are internally connected to a 32.768 kHz crystal.
*) If one of both RFOUT pads of the radio module deRFmega128-22M12 is unused, it
must be terminated with 50 ohms to ground. This action ensures the proper function
of the internal power amplifier and will reduce the power consumption.
