Hi. I confused about deep sleep on ST's Cortex M4 processor. As I understand If I use HSE as an system clock and go to deep sleep, HSE will turn off. And in wake up ST's document says HSI is used as system clock source after wake up from STOP and Standby. I tought it's because of HSI's startup time is lesser than HSE(2us and 2ms). Where I confused abaout is, after waking up should I reinitialize the clock as HSE or it will be automatically switch to HSE after stabilized.
Sorry for bad English and Thanks in advance.
