* FLAGS\r
+ *\r
+ * Taken from include/low-can/can-message.hpp in agl-service-can-low-level.\r
+ * The flags values in the generated message_definition_t definitions needs to\r
+ * match usage of these flags in the binding, e.g. in the various member\r
+ * functions in low-can-binding/can/message-definition.cpp.\r
+ *\r
+ * ATM the only flags known to be used are:\r
+ *\r
+ * CAN_PROTOCOL_WITH_FD_FRAME\r
+ * J1939_PROTOCOL\r
+ * ISOTP_PROTOCOL\r
+ * BYTE_FRAME_IS_BIG_ENDIAN\r
+ *\r
+ * Note that for BYTE_FRAME_IS_BIG_ENDIAN, even though it is referenced in\r
+ * message-definition.cpp, the member function that does so seems currently\r
+ * unused, so it is not clear what the intended usage actually is.\r
+ * The JSON parser for CAN messages would likely need an additional field\r
+ * added to allow setting it, for now that is being left for a future update.\r
