Hi,
I will use K27 with external clock mode, but I couldn't find its timing specification in the data sheet.
Could you tell me the maximum value of clock rise time and fall time?
Best regards,
M.Kiniwa

Hi Masahiro Kiniwa,
Thank you for your interest in NXP kinetis product, I would like to provide service for you.
Yes, the datasheet didn't list the detail external clock input rise time and fall time.
But in my memory, even use the chip pin output the internal clock to the external clock pin, it also works.
So, I think you also can refer to this rising and fall time to select your external clock:
If you still have problems about it when you use the external clock, please kindly let me know.
Have a great day,
kerry
