Can you suggest a keyword that I should search for to find this information?

Hi,

I'm going to be using an MPR121 capacitance chip in a touchpad application. It has 12 electrodes. I had some general questions about I2C and a sensor type chip like the MPR121:

-What happens if you try reading the MPR121 but the MPR121 is in the middle of gathering it's sensor (electrode) data?
-What happens if you try reading the MPR121 and in the middle of that the MPR121 needs to sample its electrodes at the same time?
