- When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. Therefore, power consumption changes accordingly.
- In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load and the peripherals used.
- During Deep-sleep, when the ULP coprocessor is powered on, peripherals such as GPIO and RTC I2C are able to operate.
- When the system works in the ULP sensor-monitored pattern, the ULP coprocessor works with the ULP sensor periodically and the ADC works with a duty cycle of 1%.
