MSPM0L1306: MSPM0L1306: How to check 32 KHz Low frequency

Hi Team,

I am trying to configure 32 KHz in a microcontroller. In the description, I observed the following points:

RUN1: MCLK and CPUCLK run from LFCLK (at 32 kHz), but SYSOSC is left enabled to service analog modules. RUN2: MCLK and CPUCLK run from LFCLK, and SYSOSC is disabled. This is the lowest power state with the CPU running.

Note: RUN1 and RUN2 require all HFCLK peripherals (HFXT, HFCLK_IN, SYSPLL if equipped) to be off. Thus, it is not possible to source MCLK from LFCLK and have a high-frequency external clock.

 

How can I turn off HFCLK. Can anyone please help me regarding this ASAP.
