How to generate complimentary SPWM using ATmega328 in Arduino IDE - c++

Question

Here generated complimentary PWM using ATmega328 in Arduino IDE.
The given code works well. It is generating complimentary PWM output but the problem is that one output is as desired, but the complimentary output is not as desired. Initially complimentary pin should be on HIGH and after SPWM cycles from lookUp table it should be HIGH forever till next pulse, never go for LOW. The other output is as desired, it is initially LOW and after SPWM pulses from lookUp it remains LOW till next pulses. I need to generate pulses as I attached. Also want to add deadtime.
#define MAX_COUNT 500 // (16 MHz / SW_FREQ) / 2
#define NO_OF_PULSES 160 // 16 kHz / 50 Hz = 320; 320 / 2 = 160 pulses in one half-cycle
int lookUp[NO_OF_PULSES] = {500, 490, 480, 471, 461, 451, 441, 431, 422, 412,
