Thanks @D@n, you explained even more than I hoped for, I really appreciate it. I thought that sign bit is just a timing error on my end. Those reference links seem to give me some fun time with my board.

Hi, this is my first try to interact with a chip, so please bear with me if my question is dumb. I'm using Basys3 with the pmod MIC3. The ADC gives back 4 leading zeros and 12 bits of data. I can get this out of pmod. But how to interpret this data? I understand the main principle of the ADC - I get a relative value between 0 and 2^12. The pmod's reference says that this value is representative of the volume and frequency. I assume that this is a kind of composite value, like X high bits are the frequency, and the rest are for volume, or similar - but couldn't find anything about such things. I was looking at all reference documentation and sample codes I could find, but maybe I was looking at wrong places. How do I get the volume and frequency separately out of the retrieved 12 bit value? Thanks
