Hi,
there is one, out of probably multiple choices...
This is an application report on random number generation using two asynchronous clocks on the MSP430. But the core of the functionality is a capture utilization of an MSP430 Timer. So please give it a try. www.ti.com/.../slaa338a.pdf
If you look into the pdf, the first page contains a link to the code example.

Best regards
Peter

is there's any example code in C instead of asm ?

Hi,
sorry, did not realize that one is in assembler. In CCS in the TI Resource Explorer you can find the with the MSP430F2619 the code example MSP430x261x_fll_01.c, which implements a SW FLL, utilizing Timer Capture functionality.
There is also a second example.

Best regards
Peter
