MSP430G2553: MSP430 simple IR communication

Part Number: MSP430G2553

Hi everyone.I am begginer at MSP430.;

I would like to bliknk two different leds via pressing two different buttons using IR.

I think transmitter works propperly.But something is wrong with my receiver.

unsigned int time_in_high;
int A;
 

int main(void)
{
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
    P1DIR = BIT0|BIT6;   
    P1REN = BIT3;   
    P1OUT = BIT3; 
init();

while(1)
{
listen_IR();
}
}


void listen_IR(void)
{
if((P1IN & BIT3)!=BIT3) {   //falling edge
  startTimer();}
if((P1IN & BIT3)==BIT3){   //rising edge
  stopTimer();
  A=readTimer();          //read the timer to detect PWM length
  clearTimer();
  }

if (A>8000 && A<10000){ //if transmitter sends 9ms PWM 
P1OUT^=0x01;  
__delay_cycles(500000);
}
if (A>3000 && A<6000){
P1OUT^=0x40;  // if transmitter sends 4.5ms PWM 
__delay_cycles(500000);
}
 
}


void init(void)
{

configTimer();
configClock();

}

void configClock(void)
{
//1Mhz
BCSCTL1 = CALBC1_1MHZ; // Set range
DCOCTL = CALDCO_1MHZ; // Set DCO step + modulation
}

void configTimer(void)
{

}

void stopTimer(void)
{
TACTL = 0;
}

void startTimer(void)
