Types and structures• Bits.ovr:[out] Data overrun. The bit is set to 1 if the receive FIFO is full after this messageis entered.• Bits.ido:[in] ID only. The bit is only relevant for messages of type LIN_MSGTYPE_DATAwhich are transmitted directly. If the bit is set to 1 for transmit messages, onlythe ID is transmitted without data and is therefore used in master mode tosend the IDs. With all other message types, this bit has no significance.• Bits.res:Reserved for future extensions. This field is normally 0.5.3.5 LINMSGThe data type describes the structure of LIN message telegrams.typedef struct _LINMSG{UINT32 dwTime;LINMSGINFO uMsgInfo;UINT8 abData[8];} LINMSG, *PLINMSG;• dwTime:[in/out] With receive messages, this field contains the relative receive time ofthe message in ticks. The resolution of a tick can be calculated from the fieldsdwClockFreq and dwTscDivisor of the structure LINCAPABILITIES in accordancewith the following formula:Frequency [s] = dwTscDivisor / dwClockFreq• uMsgInfo:[in/out] Bit field with information on the message. A description of the bit fieldis given in section 5.3.4.• abData:[in/out] Array for up to 8 data bytes. The number of valid data bytes is definedby the field uMsgInfo.Bits.dlen.106Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
