Other Parts Discussed in Thread: LAUNCHXL2-RM46, HALCOGEN

How do I find out the VCLK2 value for my board.?

For example, I am currently using the LAUNCHXL2-RM46, How would I go about finding the VCLK2? Also, is there a method to find its value at run-time?

    Hello Safiullah Hussaini,

    If you are using Halcogen then pls navigate through the GCM tab to find more details on how the clocks are configured.

    Once you have the clocks configured, you can also use the CLKTEST register to bring few of the clocks on to ECLK pin for external monitoring(which is meant for debugging purposes).

    Pls refer to sec 2.1.5.32  of RM46 TRM for more details.

    Some clocks may not be available for direct monitoring, in that case use the available clocks and look at the respective divider values to find the programmed ratio.

    For VCLK2 pls refer to sec 2.5.1.45 - Clock Control Register (CLKCNTL) of the TRM.

    Hope this helps.
