Hi Experts,

How to configure CLB's internal counter to be driven by some clock such as System Clock? Which Drivelib function should be used?

Thanks

Hello,

The counters are clocked at the CLB frequency. You could use an event (with mode ADD +1) to update the counter based on something occurring instead. Or you can use another counter as a divider and feed it into the EVENT signal. Would that work for you?

REgards,
Peter

Thanks, Peter. Then how do I figure out what my "CLB frequency" is?

Hello,

It is 100 MHz. For F2838x you can run up to 150MHz with CLB PIPELINE MODE enabled.

Regards,

Peter
