PSoC 4 MCU

New Contributor

Hi

I usually using sysclk as a main timer source clock in other arm cortex based MCU.

In topdesign file of the PSoC Creater4.3, I can't find the way how to use sysclk as a source of the clock component.

there is only available HFCLK .

How can I get it?

Hi,

I tried this with PSoC 4 4200M (CY8C4247AZI-M485, which is on the CY8CKIT-044).

If we double click "clocks" in the Workspace Explorer > <Project> > Design Wide Resources > Clocks

We can see the clock settings,

And if we double click the row of the clock in interest, here, I double clocked the right side area of "SysClk"

We can see the clock tree.

As you can see, the source of "SysClk" is "HFClk".

And SysClk's Divider is 1.

So I thinks that in this case, using HFClk is similar as using SysClk.
