MK70 UART Module clock

[codybennett]

I am in the process of setting up the UART Baud on an MK70FN1M0VMJ12 (custom board). I need to know how to verify/set the Module Clock frequency. It seems this is derived from the Bus clock yet I have not found a register to set or verify for the frequency.

Hello ,

Then we can refer to the clocking didagram calculate the system clock or  bus clock , please see :

And each part can be found the related register on the RM.

Hope it helps
