Using HCS12, write a C program:

2) 17 marksl The IRQ is connected to a sensor that triggers an interrupt when an event occurs, e.g., a customer enters a store. Write a C program to display the number of customers who entered the store on the 7-segment displays. Assume that this number is at most 9999. Hint: use IRO routine to update the count. In the main program, display the count on the seven segments. See the example in the slides that displays only two digits. 2) 17 marksl The IRQ is connected to a sensor that triggers an interrupt when an event occurs, e.g., a customer enters a store.
