UART1 Baud setting in PE running on KL25 Freedom board problem

I have encountered a problem that when I use the UART1 on KL25 Freedom Board on Pin18, Pin20 of connector J2 for Tx,Rx of UART1, I found the output Baud Rate is half what I set in ProcessExpert Component. For example, if I need 115200, I need to set it to 230400 in the Serial_LDD.

The CPU clock setting and the Serial_LDD settings are attached here.





I have checked it with oscilloscope and proved it by PC terminal. I am using CodeWarrior for MCU version 10.3


I hope it's helpful to be fixed in the coming version of PE.
