MSP430FR2475: Disable/close UART port on MSP430FR2475

Hello Samyukta,

As Bruce mentioned, the UART will only run with the application software configures it.  

There may be a UART BSL available for updating via a invoke sequence.  Is this possibly what you are wanting to disable?  Are you trying to disable BSL for security purposes? 

Thanks,

JD 

I have actually disabled the BSL... but I figure the UART pins which use the same SBW pins (which are also disabled) will still be functional. And yes want to disable the UART/BSL for security purposes.

I see. This is basically done in our Init_UART routine, so the idea would be to not call it at all. 

Yes, outside of the BSL, the UART cannot be operational without the application code specifically initializing it and configuring the GPIO pin mux for it, as Bruce said.
