I noticed there are two lib files in Cortex-M4 core MCU:

MC_Library_ProtectedSources_SD_CM4_CCM_MKD.lib and MC_Library_ProtectedSources_single_drive_CM4_MKD.lib

I can't find any description for the diffrence between them, so I should choice which one in my application?

thank you.

The CCM Lib makes use of the Core Coupled Memory, functions are executed from RAM (=significantly decreased critical task execution time). See also AN4296 and UM1080
