S32K358 measured baud rate of UART_1 is half of the configured value

I've configured the UART_1 of S32K358 as 115200:

And the source code generated is as below:

The clock configuration is as below:

The frequency of UART_1 is as below:

But I've measured the baud rate of UART_1 by oscilloscope, the real baud rate of UART_1 is about half of 115200. I've no idea for the reason.

Correct: the measured baud rate is double of 115200.
