Fix the broken c code. the program should blink the greenled every half second, but the red led is steadily lit. youmay not delete or add code, you may only change valuesbeing stored in a variable or register. time an iteration of the delay subroutine using the cpu timerand breakpoints.#include /* * fix this code! you may not delete or add code, you may only change values being stored in a variable or register. */void delay(); unsigned int cls(unsigned int x); unsigned int crs(unsigned int x); int main(void) { wdtctl = wdtpw | wdthold; volatile unsigned int m = 1; volatile unsigned int s = 0; volatile unsigned int p = 65535; p1dir |= m; while(s) { p = crs(p); p1out = p; delay(); }}void delay(){ volatile unsigned int i = 25; volatile unsigned int j = 0; volatile unsigned int k = 1; volatile unsigned int l = 0; for(; i > 0; { j += 2; k += 2; } l = cls(j + k); }unsigned int cls(unsigned int x){ return (x < < 1) | (x > > 15); }unsigned int crs(unsigned int x){ return (x > > 1) | (x < < 15); }
