Interrupt Source Register (03h)

The Interrupt Source register selects which ADC channel value to use to generate an interrupt. Only one of the

four ADC channels can be selected.

NOTE: The INTERRUPT THRESHOLD Register (08h−0Bh) should be configured appropriately to correspond to the ADC channel value that

generates an interrupt.

ID Register (04h)

The ID register provides the value for both the part number and silicon revision number for that part number.

It is a read-only register, whose value never changes.
