Question 19 (14 points) P and PD2 are connected with two external switches SW1 and sW2 deD1 and LED2 respectively using negative logic. The system uses er a system with two input pins PDI, PD2 and two output pins PE4. PES PE4 and PES are connected with two external default system clock frequency Q19.1 triggered interrupts. In the system, when SW1 is pressed, an edge-triggered interrupt will be generated from PD1. When SW2 is pressed, an edge-triggered interrupt will be generated from PD2. When SW1 or SW2 is released, no interrupt will be triggered. Assume there is no switch bouncing. Given these requirements, please complete the code fragment below using friendly software to configure related registers ) Assume we need to design a software program to implement edge- void Interrupt Init(void) GPIO PORTD ISR GPIO PORTD IBE_R GPIO PORTD_IEV_R GPIO PORTD IM_R Question 19 (14 points) P and PD2 are connected with two external switches SW1 and sW2 deD1 and LED2 respectively using negative logic.
