+ * @defgroup CAN CAN Driver
+ * @brief Generic CAN Driver.
+ * @details This module implements a generic CAN (Controller Area Network)
+ *          driver allowing the exchange of information at frame level.
+ * @pre     In order to use the CAN driver the @p HAL_USE_CAN option
+ *          must be enabled in @p halconf.h.
+ *
+ * @section can_1 Driver State Machine
+ * The driver implements a state machine internally, not all the driver
+ * functionalities can be used in any moment, any transition not explicitly
+ * shown in the following diagram has to be considered an error and shall
+ * be captured by an assertion (if enabled).
+ * @if LATEX_PDF
