3.2.1 Bypass Capacitors

C1_x and C3_x are 10-μF and 0.1-μF supply bypass capacitors, respectively, for the TMCS1123. These devices are present to help smooth the supply voltage of the TMCS1123. By default, the 10-μF is depopulated, but can be populated to evaluate potentially extremely noisy supplies.
