MSPM0L1228-Q1: About the BSL and LFCLK

Part Number: MSPM0L1228-Q1
Other Parts Discussed in Thread: MSPM0L1228

Hi TI Expert,

If we want to execute the BSL by UART0 in MSPM0L1228 MCU, what will be configured in our HW side?

Is the LFCLK is necessary? Or we can use HFCLK to exeuct the BSL program?
