* @brief Custom Functions Subsystem (CFS) HW driver header file.
*
* @warning There are no "real" CFS driver functions available here, because these functions are defined by the actual hardware.
* @warning The CFS designer has to provide the actual driver functions.
*
* @note These functions should only be used if the CFS was synthesized (IO_CFS_EN = true).
