Test Points & Jumper Interface¶
The xPico 600 EVB features jumper interface and a series of test points, which can help you to obtain the corresponding waveform of some signals.
The position and pin assignment of test points J0301, J0302, J0303 and jumper interface J0201 are shown in the figure below.
