I'm trying to figure out how working potentials are set on the LMP91002. The datasheet suggests that it is possible to apply reducing (negative) or oxidizing (positive) potentials at the working electrode against the reference (p. 11), and that the "internal zero" applied to the working electrode/ non-inverting terminal of TIA is set as a programmable division of Vref or the supply voltage. But then what exactly sets the potential at the reference electrode? In other words, how is the "zero bias potential" described on p. 10 set? Or can this device only be used for 0 V working potential with respect to the reference electrode?
