[nRF52840] I2C clock low time period failed

[Sheng]

Hi

 We met the problem is that clock low time period is out of spec, we got the value from oscilloscope is 1.24us@pull up resistor 10K/7.15k when clock speed=400kHz. The spec is >1.3us.

can we modify the timing in SW? How to modify it?

thanks,

It depends on the micro.  The nRF52840 does have a frequency setting.  See their errata.
