What Is Vector Table In Microcontroller -

System-level events like powering on or a processor error.

You can't avoid it. Every microcontroller has one. However, if you don't define the vectors properly: what is vector table in microcontroller

The CPU loads that address into its Program Counter (PC) and executes the ButtonPressed_ISR function. System-level events like powering on or a processor error

When a specific event occurs (like a reset, a hardware interrupt, or an error), the microcontroller’s CPU pauses what it is doing, looks up the corresponding address in the Vector Table, and jumps to that location to execute the code. However, if you don't define the vectors properly:

When you press the "Reset" button on a microcontroller development board, magic seems to happen. The LEDs light up, the screen initializes, and your code begins to run. But how does the processor know where your code starts? How does it know what to do when a timer overflows or when you press a button?
