Hello @plefebvre1,

Could you please check the following community post: Power Management on Kinetis MCUs: LLS and VLLS mod... - NXP Community? There is explain how to use the System Register File and could be useful to take a look at.

For the K32L2B, this System Register File's base address is 0x4004_1000 and it can be seen in K32 L2B Sub-Family Reference Manual. Table 4-4. Peripheral bridge 0 slot assignments.

Warm regards, Raul.
