How to Generate Clock Output (MCO1/MCO2) on STM32H573

In embedded systems, sharing clock signals externally is often essential for synchronizing peripherals or other microcontrollers. Most of the popular Microcontrollers often need to share their internal clock signals with external components. The STM32H573 supports this via Microcontroller Clock Outputs (MCO) on two GPIO pins: PA8 (MCO1) and PC9 (MCO2). Whether you’re debugging clock issues or […]

MCU Startup Code: What Happens Before main() Runs (ARM Cortex-M Example)

MCU Startup code is the first piece of code executed by a microcontroller (MCU) immediately after a Power-On Reset (POR). Its main responsibility is to prepare the MCU’s hardware so that the actual application can run smoothly. The main purpose of start-up code initializes critical components such as the stack, system memory, and configuration settings.
