MSP430G2553: Bidirectional Motor control with MSP430G2553

Hello, I have started programming the MSP430G2553 recently. I am trying to make the dc motor rotate in either direction with a push of a button. The motor driver I am using is L293D. I got it to spin in 1 direction, but when I try to spin it in the other direction, it keeps on spinning in the original direction. I know that the motor is capable of spinning in the other direction as I switched the cable around and it worked.

Here is the code:

void main(void)
{
    WDTCTL = WDTPW + WDTHOLD;           // Stop Watchdog
    if (CALBC1_1MHZ==0xFF)              // Check if calibration constant erased
    {
        while(1);                       // do not load program
    }
    timer_init();

    // configuring button interrupt
    P1DIR &= ~BIT3;                       // Set SW pin -> Input
    P1REN |= BIT3;                        // Enable Resistor for SW pin
    P1OUT |= BIT3;                        // Select Pull Up for SW pin

    P1IES &= ~BIT3;                       // Select Interrupt on Rising Edge
    P1IE |= BIT3;                         // Enable Interrupt on SW pin
    P1IFG &= ~BIT3;                     // clear the flag


    // pwm motor port config
    //Motor Control pins
    P2DIR |=  BIT0 + BIT1 + BIT2;   // P2.0,P2.1,P2.2 all output
    P2OUT &= ~BIT0;   // Clear P2.0,P2.1,P2.2
    P2OUT &= ~BIT1;
    P2OUT &= ~BIT2;
    while(1)
    {    }
}

Here is the timer config

    //pwm timer config
    TA1CCTL1 = OUTMOD_7;            // TACCR1 reset/set
    TA1CCR0  = 1000-1;        // PWM Period
    TA1CCR1  = 300;            // TA1CCR1 PWM Duty Cycle
    TA1CTL   = TASSEL_2 + MC_1 + ID_0 + TACLR;     // SMCLK, upmode

    // Global Interrupt Enable
    _BIS_SR(GIE);

And finally, the button interrupt

#pragma vector=PORT1_VECTOR
__interrupt void Port_1(void)
{
    if (P1IFG & BIT3) // make sure it's button interrupt
    {
        if (select == 0)  // turn motor on 1 way
        {
            select = 1;
            P2SEL |= BIT1;   // pwm P1A
            P2OUT &= ~BIT2; // P2A low
            P2OUT |= BIT0;  // select enable
        }
        else if (select == 1) // turn off motor
        {
            select = 2;
            P2SEL &= ~BIT1;
            P2SEL &= ~BIT2;
            P2OUT &= ~BIT1;
            P2OUT &= ~BIT0;
            P2OUT &= ~BIT2;
        }
        else if (select == 2)  // turn on motor the other way
        {
            select = 3;
            P2SEL |= BIT2;   // P2A pwm
            P2OUT &= ~BIT1;  // P1A low
            P2OUT |= BIT0;   // select enable
        }
        else                // turn off motor again
        {
            select = 0;
            P2SEL &= ~BIT1;
            P2SEL &= ~BIT2;
            P2OUT &= ~BIT1;
            P2OUT &= ~BIT0;
            P2OUT &= ~BIT2;
        }
        P1IFG &= ~BIT3;  // clear interrupt flag
    }
}

I have P2.0 connected to the EN of the L293D, P2.1 and P2.2 are connected to P1A and P2A, respectively.
