WebA software reset via NVIC_SystemReset works correctly. The STM32H753 reference manual section 8.4.2 Figure 43 shows that a watchdog reset will cause a transition on the external NRST pin, as will a software reset. I have prepared an absolute minimal example showing that this is not the case. WebSpecifies the priority level for the IRQ channel specified. in NVIC_IRQChannel.

Web3 okt. 2024 · NVIC in ARM Cortex-M3 (ARMv7-M) implements fixed 8-bit priority fields in Interrupt Priority Register ( IPR ), thereby giving us up to 256 (2 8) priority levels. But, not all of the ARM Microcontrollers implement 8 bits for priority levels, in which case the remaining priority bits are treated as Zeros because the field size is fixed to 8 bits. http://stm32f4-discovery.net/2014/05/stm32f4-stm32f429-nvic-or-nested-vector-interrupt-controller/
