+/* CAN
+ *
+ * Connector 10 (CN10) is DB-9 male connector that can be used with CAN1 or CAN2.
+ *
+ *   JP10 connects CAN1_RX or CAN2_RX to the CAN transceiver
+ *   JP3 connects CAN1_TX or CAN2_TX to the CAN transceiver
+ *
+ * CAN signals are then available on CN10 pins:
+ *
+ *   CN10 Pin 7 = CANH
+ *   CN10 Pin 2 = CANL
+ *
+ * Mapping to STM32 GPIO pins:
+ *
+ *   PD0   = FSMC_D2 & CAN1_RX   
+ *   PD1   = FSMC_D3 & CAN1_TX   
+ *   PB13  = ULPI_D6 & CAN2_TX
+ *   PB5   = ULPI_D7 & CAN2_RX
