Hi Infineon.

 

Could you please let us know how to use external clock instead of internal clock on PSoC 4000S?

 

Can user use external clock by following 2 steps?

Are there any other steps required to use external clock, such as adding code other than below 2 steps?

 

If user implement below 2 steps, will the clock source be switched from IMO to external clock?

If user implement below 2 steps, will IMO stop and switch to PSoC operation using external clock?

 

 

=========================================================

Step 1:

Check EXTCLK to enable external clock.

Change HFCLK source from IMO to EXTCLK in the pull-down menu.

Step2:

Connect an external clock to P0_6.

Hi @YuMa_1534086 

Yes, there are no additional steps required.
Are you facing any issues when setting Extclk as the source of HFCLK?

Ekta-san.

 

Thank you for your support.

This does not mean that there is any particular problem.

I confirmed setting method just to make sure.
