7.6.12 Control Enable

The Control Enable register contains the bits to turn on/off the individual Control Banks (A, B, or C). Once one of

these bits is programmed high, the current sink(s) assigned to the selected control banks are enabled.

7.6.13 ALS1 and ALS2 Resistor Select

The ALS Resistor Select Registers program the internal pulldown resistor at the ALS1/ALS2 input. Each ALS

input has its own resistor select register (ALS1 Resistor Select Register, Address 0x20) and (ALS2 Resistor

Select Register, Address 0x21). Each ALS input can be set independent of the other. There are 32 available

resistors including a high impedance setting. The full-scale input voltage range at either ALS input is 2V.
