30      Two pins are available that can be configured as either a general purpose
31      digital output, device enable signal (used to synchronise other parts of
32      the signal chain with ADC sampling), device ready (GP1 only) or various
33      interrupt signals. If intended for use as a GPIO or device enable, will not
34      present here.
