自己按着 reference 就是进不去功耗还是有100多uA
/**
* 1. Jump to RAM √
* 2. Switch system clock to LSI or LSE clock sources √
* 3. Switch off the high speed oscillators, the ADC and all unused peripherals --
* 4. Mask all interrupts √
* 5. Switch off the Flash/Data EEPROM by setting EEPM bit in FLASH_CR1 register √
* 6. Add a software delay loop to ensure Flash/Data EEPROM off status
* 7. Configure the ultra-low-power mode for the regulator by setting the REGOFF bit in the CLK_REGCSR registe

特别是加了
CLK->REGCSR |= 0X02;
while(((CLK->REGCSR)&0x01)==0x01);
之后电流直接到了 6mA
