about ARM baud rate

Note that NXP (among others) divide the documentation for their processors between 2 documents:

The Datasheet defines the physical paratemers - electrical, timing, package dimensions, etc;

The User Manual describes the internal workings of the chip - peripherals, registers, etc.

I suspect that details of how to use the UART - including, of course, how to set its baud rate - will be found in the User Manual

Note that NXP (like any other manufacturer) also provide numerous Application Notes and Examples that describe and illustrate the use of their chips...
