About core clock deviation

Thank you for your help.

KM14 series uses SLOW CLOCK for core clock, 41.94MHz
Use as. At this time, the data sheet states that the SLOW CLOCK error is ±2%, so will the core clock also deviate like that?

thank you.

Hi,

Regarding the internal slow reference clock, I have checked the data sheet, the slow clock ranges from 31.25KHz to 33.4234KHz with +/-4% deviation typically, and +/-15% at most.

Pls check if you use internal slow or fast clock.

If you use the internal clock as core clock, of course, the core clock will deviate like the original one, but it does not take effect on the core operation.
