3.2.1.1.2.15 CAN_FIFO_BASED_TRANSMIT_PRIORITY_FEATURE_AVAILABLE

CAN_FIFO_BASED_TRANSMIT_PRIORITY_FEATURE_AVAILABLE

#define CAN_FIFO_BASED_TRANSMIT_PRIORITY_FEATURE_AVAILABLE 1

This macro defines the CAN FIFO based transmit priority data update request functionality.

APIs Supported:

CAN_TX_MSG_REQUEST_STATUS CANx_Transmit(const CANx_TX_FIFO_CHANNELS fifoChannel, CAN_MSG_OBJ *txCanMsg); CAN_TX_FIFO_STATUS CANx_TransmitFIFOStatusGet(const CANx_TX_FIFO_CHANNELS fifoChannel);

x denotes instance of CAN in CANx. Refer to device specific datasheet to check number of CAN module instance. Refer driver header file for detailed description of the APIs.
