Fix the broken C Code The program should blink the Green LED

Fix the broken C Code. The program should blink the Green

LED every half second, but the Red LED is steadily lit. You

may NOT delete or add code, you may only change values

being stored in a variable or register.

Time an iteration of the delay subroutine using the CPU timer

and breakpoints.
