Low Power Dissipation Reference Design
Normal Power Dissipation Reference Design
1. GPIO1 is the interrupt signal of SDIO, It must be connected, If unconnected
throughput will be decrease.
2. PMU_PWRON is enable pin of the module. It must be high before power on.
3. Wake up must be connected, non-power-saving applications also need to connect.
