Suppose port 1 pin 1 is connected to a switch (interrupt enabled) on MSP432 board, and port 1 pin 0 is connected to an LED. When the switch is pressed, an LED will toggle 1. The event (switch is pressed) can be detected by using what mechanisms? What are the differences between these mechanisms? 2. Complete the missing code at" * to implement the function with the variables GPIO_PORT_P1, GPIO_PINO, GPIO_PIN1, INT_PORT.1.
