J6 allows measuring the internal 1.8V supply to the EcoXiP flash by measuring the voltage
drop over a 20 milliohm resistor.

SP2c: VBAT Powering
The picture below illustrates where the VBAT input connector is (J2) and where the current can be
measured over a 1 kohm resistor, J26. The arrow indicates the current flow direction.
