Could you please explain me what are the steps to enter into stop mode ? Currently, I write "1" into SLEEPDEEP. SMC registers (STOPCTRL and STOPM) are configured to enter to STOP mode when Sleep-On-Exit or Sleep-Now mode is entered with SLEEPDEEP = 1 (cf datasheet). But what is actually Sleep-On-Exit and Sleep-Now ? and how can we set them ?
