Hi Arslan,
My colleague gave me some info on this. For the MSP430, your peripherals are running off of a different clock source. You need to configure the clock frequency of the following module:
ti.sysbios.family.msp430.ClockFreqs
Please see the document page for 'ti.sysbios.family.msp430.ClockFreqs'. It's in the BIOS API guide, found in your SYS/BIOS installation (e.g. I have it here: bios_6_40_01_15\docs\Bios_APIs.html). It has a detailed explanation:
