Hi prashanth k b,

MSP430G2333 does not have LPM3.5. LPM4 is the lowest power mode that device offers. The device can wake from a GPIO in LPM4. However LPM4 disables all the clocks which means you will not be able to run the timer in LPM4. If you use LPM3 (which has ACLK running) you can wake from a timer interrupt.
