MKL16 UART1 baud rate clock path / 57600 limit

In a Processor Expert project (no SDK), I see UART0 clock path is pretty normal, but for UART1 and UART2 the OUTDIV4Presc scalar of 2 is preventing speeds over 57600.

 

OUTDIV4Presc seems to be associated with flash configuration (see 3rd screenshot). Why is this in the clock path for UART1? Is there a speed limit on UART1 and UART2?

 

Thanks
