 EFM32 combines this with quick wakeups and efficient processing to reduce the impact of the CPU when code needs to be executed.A good example of a deep sleep peripheral on EFM32 is the "Low Energy Sensor Interface" (LESENSE), which is capable of duty-cycling inductive, capacitive, and resistive sensors while autonomously operating in Deep Sleep mode.Another important aspect of the Gecko MCUs is that the peripherals have a direct connection between each other, allowing them to communicate without CPU wake up and intervention.
