QuickSense C8051F990 Low Power MCU with Capacitive Sensing Slide 9
The wake-up time of the MCU is a very important aspect of low power system design. The wake-up time is the amount of time it takes the MCU to start executing instructions from the low power mode and is dependent on which mode the MCU is exiting. Another extremely important aspect of low power systems relating to wake-up time is the analog settling time requirement.  Many applications wake-up and take an ADC reading and go back into sleep mode so it is not sufficient to just look at the digital wake-up time anymore. The analog system needs to be up and ready to take a measurement quickly so the MCU can return to the low power state.
