`CANMSG_UNUSED`	This define holds the coding for the information: 'message not used'. This status is the default status, before the CAN message initialization function is called. After the CAN message initialization, this status remains in the CAN message interface slots, which is not configured via the configuration structure.
`CANMSG_TX`	This define holds the coding for the information: 'transmit message'. This status will be set, after a signal is created with a corresponding transmit configuration.
`CANMSG_RX`	This define holds the coding for the information: 'receive message'. This status will be set, after a signal is created with a corresponding receive configuration.
