IDO-SOM2D01 Core board power management
According to the power supply timing requirements of SSD201, the core board leads out two core board power supply pins(SYS_3V3，AVDD_RTC).
VDD_RTC (96PIN core board) must be powered for a long time, and the standby battery is powered for a small current consumption. After shutdown, maintain the internal RTC power supply with a current of 1uA.
VCC_SYS (core board 1PIN) is the main power supply for the core board, with a supply voltage of 3.3V and a peak current of 400mA.
