STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
At the end of NVIC_SCBDeInit I see these instructions:[...]SCB->CFSR = 0xFFFFFFFF;SCB->HFSR = 0xFFFFFFFF;SCB->DFSR = 0xFFFFFFFF;The first one is a status register. Why writing it?For the second one the manual states:"This register is read, write to c...
Hello,I read ref manual part about SYSCFG (STM32H7 in my case). There are some regs that have an undefined reset value and the meaning of the regs is so that the contents is important at HW reset (BOOT_ADDx, BANK_SWAP). These regs are marked read onl...

I use dual flash bank in STM32L4. I perform a flash bank switch by programming bit BFB2 in OPTR.Sometimes, after the new software has started, RTC seems to be returned to reset state: date and time are lost and RTC internal registers are cleared! In...
