S32K312 I2C speed

I use the I2c_SyncTransmit function.

and I2C speed is 400Khz (LPI2C_FAST_MODE)

At init, the operating mode is LPI2C_FAST_MODE,

but when I2c_SyncTransmit is executed, it switches to LPI2C_STANDARD_MODE.

Lpi2c_Ip_SetMasterHighSpeedMode <- This function sets OperatingMode to LPI2C_HIGHSPEED_MODE or LPI2C_STANDARD_MODE.

I want LPI2C_FAST_MODE.

Hi @kjy106906 

I ask you to please clarify how you are checking that in I2c_SyncTransmit, the I2C mode switches to LPI2C_STANDARD_MODE.
