I know it is a multi-part question, I'll take any help possible.

Prob 10. (25 points, 5 each) We can better understand the code when we can explain each part easily. Consider the single-line code below for checking if the pushbutton (a key) connected to Pin1 of GPIOA is pressed or not: bool PA1_state =(( GPIOA->IDR \& GPIO_PIN_1 )== GPIO_PIN_1 1); 1. (5 points) What is the value of ? 2. (5 points) If the key on PA1 is pressed and the value in IDR corresponding to Pin 1 is 1 , what is the value of GPIOA->IDR \& GPIO_PIN_1? 3. (5 points) (Continue Part 2.) What is the value of (GPIOA->IDR \& GPIO_PIN_1) == GPID_PIN_1 ? 4. (5 points) If the key on PA1 is released and the value in IDR corresponding to Pin 1 is 0 , what is the value of GPIOA->IDR \& GPID_PIN_1? 5. (5 points) (Continue Part 4.) What is the value of (GPIDA->IDR \& GPID_PIN_1) == GPID_PIN_1
