    IMO clock trimming


      I'm using a CY8C4248LTI-L485 device and I'm observing a +/-2% clock acccuracy for IMO clock. Is it possible to trim this clock during production (using programmers tools) to obtain a better resolution?


      Thank you

          Hi RoCa_1222471,


          You can use an external WCO to trim the IMO in PSoC Creator.  There is no option to trim IMO during production using programmer tools.


          To do this:


          1. Choose Clocks tab in design wide resources.

          2. Click on edit clocks.

          3. Under low freq clocks Enable WCO (external)

          4. Under high freq clocks, in IMO, choose trim as WCO from drop down.
