The Quectel E200U has two SDIO ports one is working at 3.3V power domain and other one is working at 1.8V power domain. The eMMC VCC is 3.3V and VCCQ is 1.8V. I am new to eMMC. This is my first design with eMMC. I have two questions here. To which SDIO in EC200U do I need to connect the eMMC,1.8V SDIO or 3.3V SDIO. What is the difference between VCC and VCCq
