MSP430FR5969 identifier "BCSCTL1" is undefined, identifier "DCOCTL" is undefined

Other Parts Discussed in Thread: MSP430FR5969

I do not understand why this error occurs. 

CALDCO_16MHZ; // Set uC to run at approximately 16 Mhz
BCSCTL1 = CALBC1_16MHZ;

Also the above variables are undefined when uncommented. Please tell me what should be the right way to initialize these variables in the above MSP430.

Thank you

    MSP430FR5969 uses Clock System (CS) Module, not Basic Clock Module, nor Basic Clock Module+. Consequently, it does not have "BCSCTL1" and "DCOCTL".

    Read Chapter 3 Clock System (CS) Module of SLAU367F–October 2012–Revised January 2015

    Unfortunately you haven't actually posted a link here --- it's just underlined blue italic text!

    The family user's guide for any MSP430 can be found on the product page for that device (this link is right under the datasheet link). So if you click on the MSP430FR5969 <- this link, it will take you right to the product page.

    Additionally, posting direct links to documentation here can result in broken links in the future when website changes or new version of document is released, which frustrates people in the future finding this by search and hoping the answer helps solve their problem.
