Configuration of ADAU1467 multipurpose pins MPx
Hello,
I am using EVAL-ADAU1467Z and SigmaStudio+ 2.3.0. In the user guide, one can read that MP15, MP14 and MP7 are connected to DIP Switch S3. These pins are dedicated IO pins, i.e. not multiplexed with any other signal. However, I am struggling to configure them in SigmaStudio.
What is the difference between "Multipurpose" and "Multipurpose 1"?
Both sections seem to list the MP pins but with different naming, e.g. MP0_x vs. MP0_x1. Section "Multipurpose" lists MP pins from 0 to 13. "Multipurpose 1" lists MP pins from 0 to 11. MP14/MP15 are nowhere visible....
Best regards,
Ak
