Hi @ganavi1
If you are working with the RTD driver, the low‑level driver is the C40_Ip driver. For the high‑level driver, depending on the RTD version you are using, it may be either the Fls driver or the Mem_43_INFLS driver. Example codes are also included within the RTD package.
Additionally, you may refer to Application Note AN13388: S32K3 Memories Guide for further guidance.
