Part 6: Writing Software [6 Points] 1. [3 Points] Write a program that multiplies the content of the memory location 0x44 by 5. 2. [3 Points) Write an ISR labeled interrupting, that does the followings: a. Clears the INTF bit b. Lights 4 LEDs connected to bits 4, 5, 6, 7 in PORTB, by writing logic 'l' to these bits Calls a delay subroutine called 'delay10' d. Switches off LEDs connected to bits 4, 5, 6, 7 in PORTB Resets GIE bit and return to the main program C. e
