Help with if touch than stays on and than touch again to stay off. In C

//the two lines below make a simple turn-on while still touching, off when not touching //Chnage the code so that with every touch, LED3 toggles and stay

if(touch > touchroom * 0.9) { P2OUT &= ~BIT0; __delay_cycles(200); } // off

if(touch < touchroom * 0.7) { P2OUT |= BIT0; __delay_cycles(200); } // on }
