adau1701 digital output pin
i'm a user using adau1701 and the evluation kit.
I tried to use mp6 pin(GPIO) to get the digital output from an analog input in the evaluation kit.
However, in the evaluation kit(EVAL-ADAU1701 MINIZ), I think all the GPIO pins which can be used for digital output are already used for the other purpose except only MP6, but I think MP6 pin in the evaluation kit has no connecter.
My problem is that I want to get a digital output from an analog input by using the evaluation kit.
MP7, MP8, MP9, MP10,MP11 can be the digital output port, but they are used on other purpose in the evaluation kit.
The only left pin MP6 has no connecter outside.'
I need to make a new circuit myself ?

The EVAL-ADAU1701MINIZ provides access to the serial input port but not to the serial output port. So, yes, you're correct that MP6 is not connected to an external header. It could be possible for you to modify the board in such a way that you could make an external connection to SDATA_OUT.
The reason for this is that the EVAL-ADAU1701MINIZ was meant to be a very small, self-contained evaluation kit. The full evaluation kit, which contains a full range of digital and analog I/O, as well as full access to all GPIOs, is the EVAL-ADAU1401EBZ.
You can see the descriptions of the two boards on our website here: http://www.analog.com/en/embedded-processing-dsp/sigmadsp/processors/sigmadsp_evaluation_boards/fca.html
