I2C Timing Configration

[DK3]

Hi,

Please tell me about I2C timing configration.

I use Nucleo-L552ZE-Q.

I set up the I2C as shown in the picture following the reference manual(RM0438, Table 326).

The fi2cclk is 48MHz.

But SCL cycle is very slow. 

How can I set the SCL cycle to 1000 kHz ?

Best regards.
