Error while generating a 10kHz sine PWM using MSP430G2553

Please help,

 I am working on MSP430G2553 for generating a sine PWM of 10 KHZ inorder to drive a full bridge inverter. When i tried to load, the waveform obtained is not repeating in nature. Can you please suggest me a possible solution for the same.

Looking forward for your reply.

The source code used is provided below.
