MSP430F2012 PWM with momentary switch and interrupt function

Hello all,

I am new to the msp430, and am struggling with a current program. I can output a 5ms x 10ms on P1.2 as desired, would like to use an interrupt function to output a specific  X number cycles (periods). Also I would like to use a momentary switch to start the software ( for hardware implemenation later on). Can you provide me examples or help me with the provided code.

#include <msp430f2012.h>

#include <msp430.h>

int main(void)               //PWM 5ms x 10ms (PWxP) for 1000 cycles
{

  WDTCTL = WDTPW + WDTHOLD;  //Stop WDT
  BCSCTL1 = CALBC1_1MHZ;     // Set range
  DCOCTL = CALDCO_1MHZ;      // SMCLK = DCO = 1MHz
  P1DIR |= 0x0C;             //Set P1.2 and P1.3 to output direction
  P1SEL |= 0x0C;             //Declares TA1 a
  TACTL= MC_1 + TASSEL_2;    //Tells CCR0 to count up with SMCLK
  TACCTL1=OUTMOD_7;          //Sets Set/Reset Mode with TACCR1
  TACCR0=10000-1;            //Set CCR0 to 100 Hz (10ms Period)
  TACCR1=5000-1;             //Sets 50% duty cycle

while(1)
{

}}

Thanks
