Notice：
 ACTIVE mode， the power dissipation value is tested in MCU and WLAN activing.
 S
TANDBY 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 interrup
