Driverlib gives wrong MCLK value

I have used a code written for MSP430 tutorial to run the MSP430F5529 Launchpad MCLK at 8MHz.

I used the code below as a separate C file to initialize the clock and in the main program it just blinks it every second. Unfortunately when I set a breakpoint and watch the value of "myMCLK ", It shows a value of 8,192,000Hz after initialization. I was expecting to get a value of 8,388,608Hz which which should be the case when we set the value of UCSCTL2 to 249 . Where did this value come from?
