Please answer number 1 In our class meeting, we have discussed how to use EXTI interrupt to detect the push buttonsignal (GPIO pin PC 13) and toggle the green LED (GPIO pin PA 5) when the button is pressed.Answer the following questions will help you enable external interrupts (EXTI) to detect a signalevent external to the microcontroller. Please provide your answer in C/C++ language (Withoutthe APIs from Mbed system).1. To enable an interrupt, software needs to enable the interrupt. Software needs to perform twooperations:enable the corresponding interrupt of the Cortex-M interrupt controller (NVIC), andenable the interrupt of the corresponding peripheral (set the Interrupt Mask Register).If only one of them is performed, the interrupt is not enabled. Find out the corresponding operationsthat software must perform to enable an EXTI interrupt on the GPIO pin PC 13, which is connectedto the push button.2. What is the name of the interrupt handler corresponding to EXTI 13? (Provides thefunction/subroutine name)3. How to program the SYSCFG external interrupt configuration registers (SYSCFG_EXTICR) tomap EXTI 13 to GPIO pin PC 13? The push-button is connected to PC 13.
