MCU Hangs on register write

[zmEE22]

Hi,

I am trying to program the MK64FX512VLQ12 microcontroller.

When I program the UART0_C1 register directly, I find that the microcontroller immediately begins to hang.

I tried to attach my mode but the forum wouldn't let me.

I dropped it below.

Thank you for the help!

Hi,

Can you please put your project in an archive and attach it here ?
