We are using ADXL362 for a medical application. I needed to ask you that datasheet says it is recommended to power it up with GPIO. I wanted to ask you how important is that. I was planning to connect 0.1 uf and 10 uF caps in parallel to the power pins Vs and VDDI/O. Can you please tell me which is better scheme. Basically , bypass caps and connect it to system power - That is what I wanted to do. Since RF is involved on the circuit I wanted to make sure there are no serious issues with not using GPIO to power up. WE are using EFM32 processor.
