These make up the bulk of the table. Every MCU has different peripherals, so these vectors will point to handlers for: External button presses. UART/SPI/I2C: Data communication events. ADC: When an analog-to-digital conversion is finished. Why is the Vector Table Important?
Understanding the Vector Table in Microcontrollers If you’ve ever wondered how a microcontroller (MCU) knows exactly what to do the moment you flip the power switch—or how it manages to react instantly when you press a button—the answer lies in the . what is vector table in microcontroller
The vector table would contain a list of addresses like this: These make up the bulk of the table
