Resistive Load Selection

J1

J1 Top Pin: NA

Connect the middle pin of J1 to the top pin of J1 to source up to 10mA into VREF_F and VREF_S which are shorted together. Connect the middle pin of J1 to the bottom pin of J1 to sink up to 10mA current from VREF_F and VREF_S which are shorted together.
J1 Middle Pin: VREF_F (Pin 7)
J1 Bottom Pin: NA
