Two pins are available that can be configured as either a general purpose

|
digital output, device enable signal (used to synchronise other parts of
|
|
the signal chain with ADC sampling), device ready (GP1 only) or various
|
|
interrupt signals. If intended for use as a GPIO or device enable, will not
|
|
present here.
