Hi,

Are you still facing communication problems with MCU? Please confirm.

Please always follow our guidelines while designing the custom board with our silicon. You can use our DVK as a reference for your design.

Thanks,
Ajeeth

I have connected VCC_A and VCC_D to Vreg. It is no longer a problem.
