| struct IfxEray_Header |
| Data Fields | ||
|---|---|---|
| IfxEray_BufferDirection | bufferDirection | selects buffer as a transmit buffer or as a receive buffer. |
| boolean | bufferServiceEnabled | wether buffer service request is enabled or not. |
| boolean | channelAFiltered | channel A serves as a control for transmit and filter for receive buffers. |
| boolean | channelBFiltered | channel B serves as a control for transmit and filter for receive buffers. |
| uint8 | cycleCode | the cycle set used for cycle counter filtering. |
| uint16 | dataPointer | pointer to the data section of message buffer in RAM. |
| uint16 | frameId | slot ID of the selected Message Buffer. |
| uint8 | payloadLength | length of data section. |
| boolean | startupFrameIndicator | whether startup frame is indicated or not. |
| boolean | syncFrameIndicator | whether sync frame is indicated or not. |
| IfxEray_TransmissionMode | transmissionMode | transmission mode of Header. |
| boolean | transmitPayloadIndicatior | weather payload indicator is set or not. |
| struct IfxEray_ReceivedHeader |
| Data Fields | ||
|---|---|---|

| uint16 | frameId: 11 | received frame id. |
| uint16 | headerCrc: 11 | received header crc. |
| uint8 | nullFrameIndicator: 1 | 0 : no data frame received; 1: atleast one data frame received. |
| uint8 | payloadLength: 7 | received payload length. |
| uint8 | payloadPreambleIndicator: 1 | 1 : received payload segment has network management and message id or not; 0 : It hasn't. |
| uint8 | reservedBit: 1 | state of the received reserved bit. |
| uint8 | startupFrame: 1 | 0 : received frame is not a startup frame ; 1 : receive frame is a startup frame. |

| Data Fields | ||
|---|---|---|
| uint8 | bufferIndex | buffer index in the Message RAM. |
| boolean | dataTransfered | whether data is transfered from input buffers to Message RAM or not. |
| boolean | headerTransfered | whether header is transfered from input buffers to Message RAM or not. |
| boolean | transferRequested | transmit buffer released for transmission or not. |
