(1) The generated reference current can be observed at the TEST_MUX output pins. The target is 100 μA. These bits can be

used to tune the general reference back to target values, in case production parameters spread leads to strong deviation.

Further these bits can be used to reduce overall power consumption, though the reference voltages, (namely ADC zero

reference will drift from target values) and may have to be over driven to get proper operation at lower overall current.

(Register 0x0A, channel 0x0F).
