Hi,I used S32K144 EVB to debug LPI2C(PTA2,PTA3),configured baudrate 100kHz,system clock is ok,but I found on the oscilloscope that its baud rate is only about 90kHz(include my project and the S32DS S32K144 example( S32K1XX RTM SDK V3.0.0 example:lpi2c_master_s32k144))。I changed the LPI2C baud rate 400kHz,or set its operatingMode in LPI2C_FAST_MODE,all of them can not solve problem and baut rate can't same with configured。The S32DS example of LPI2C of s32k144 is wrong?How can I solve it?Whether it effects normal communication?

Hope to help answer me。Thank you!
