用的是外部低速振荡器32.768KHZ
手册写低功耗运行*于32kHz功耗5.4微安
软件怎么进入低功耗运行(Low-power run)模式?
5.6.1 Entering Low power run mode
This mode is entered by executing the following software sequence:
1. Jump to RAM(什么意思?)
2. Switch system clock to LSI or LSE clock sources
3. Switch off all peripherals, oscillator (except LSI or LSE) and analog blocks (except RTC
and one peripheral e.g. TIM1)
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 ultralow power mode for the regulator by setting the REGOFF bit in the CLK_REGCSR register
软件如何实现?求助!!!
