Issue of using same channel of timer TM_TA0.x

Hello All,

I am working on msp430f67641 mcu. 

I am confuse about using the PWM in UP_mode and Capture in Continue_Mode of same channel.

my setup:- 

PWM :-  P3.3/PM_TA0.2

Capture Mode :- P1.1/PM_TA0.1/VeREF+/A1

i  using PWM for the LED brightness control and Capture mode for the audio detection. When running the separate code it is working fine but when i merge it is not working.

My code:- 

void mic_init(void)
{
     TA0CTL = TASSEL_2 + MC_2 + ID_3; // Timer A 0 with SMCLK @ 8MHz, count UP
    TA0CCTL1 |= CM_1 + CCIS_0 + SCS + CAP + CCIE; // Raising Edge + CCI0A + Sync + Capture Mode + Interrupt enable

     // MIC pin intialize
    P1DIR &= ~(BIT1); // make the pin as input
    P1SEL |= (BIT1); //set this bit as Input Capture (TA0.CCI0A)

    _BIS_SR(GIE); // Global interrupts enabled
    prev_count = TA0R; // save the previous count
}

void rgb_led_pwm(void)
{
     // Configure RGB Led Pins As Output and PWM control
   P3DIR |= BIT3;
   P3SEL |= BIT3;

  TA0CCR0 = 5000-1; // PWM Per`iod
  TA0CCTL2 = OUTMOD_7; // CCR2 reset/set
  TA0CCR2 = 0; // CCR2 PWM duty cycle
  TA0CTL = TASSEL_2 | MC_1 | TACLR; // ACLK, up mode, clear TAR
}

I am stuck here..give me the solution...
