There are several ".m" files like so PlatformSDK_S32K3_2022_03/SW32K3_RTD_4_4_2_0_0_D2203/Adc_TS_T40D34M20I0R0/generate_PB. What are ".m" files? I presume that they are inputs to a template engine of some kind. What template engine/tool can process these files and what is the format of the template language?
