Question 4 If any, which line of code is problematic to the function of LEDs toggling? 1#include 3#define TCNTCONST 10000 4 5// Non-blocking using timer interrupt implementation 6 int main(void) f 7 WDTCTL WDTPW WDTHOLD - // Stop watchdog timer 8 II Upon reset CPU frequency is 16MHz // Set P.0 and P3.1 to output direction.
