Notice：
◼ ACTIVE mode， the power dissipation value is tested in MCU and WLAN activing.
◼ STANDBY mode ，MCU is in sleep，can be awakened by peripherals。 For example：When
the system has no task for a long time and needs to be connected to the network, close
most peripherals, retain the network communication capacity, and wake up the system for
processing as soon as possible when the data is received.
◼ HIBERNATION mode retains only RTC, waiting for Timer or wake-up IO interrupt
