Hi,

I want to use External Clock for KEA-128?What are the settings for that?

Hi VIGNESH,

Please refer the "Example: 20.5.3.1 FEE mode initialization routine" in KEA128RM.

You can also create a Processor Expert Project by using the KDS3.2 .

The Processor Expert will help you configure the setting.

Best Regards,

Robin

Hi,

This mode Explains to use External Clock as Internal Clock Reference.

Can you Explain me how to select the External Clock directly as the Bus Clock Out????

Hi VIGNESH,

If you want to select the External Clock directly as the Bus Clock, please select FBE or FBELP as ICS mode.

Best Regards,

Robin

Hi Robin,

Can you please tell me the difference between FBE and FBELP Mode?

As far as my understanding, FBE Mode has FLL Enabled and FBELP mode has FLL Disabled and due to this I am getting

Confused Between FEE and FBE also, Since both of them are having FLL enabled.

If you can explain me the flow of clock using block diagram and dotted lines for all three, It would be great.
