Notes: 1. Not necessary if supplied RefClk level is within specification range
2. If no AUX regulator is used, then T1 and C16 can be removed and a jumper is needed from the collector to the
emitter pad. Additionally, pin 7 of the ATR2406 has to be connected to pin 4 or pin 5 to use the integrated F
antenna, set jumper R2 (0R resistor 0603)
