Field	Field Type	Description	Format	Binary Bytes	Binary Offset
1	Log header	USERI2CRESPONSE header For information about log headers, see ASCII, Abbreviated ASCII or Binary.	-	H	0
2	DeviceAddress	The 7 bit address of the I2C device. Valid values are 0 through 127. For ASCII and Abbreviated commands, this field is a hexadecimal string of two digits. There is no 0x prefix and spaces are not allowed in the string.	Uchar	11	H
3	RegisterAddress	The actual register address used for the operation. This is a ULONG value in hexadecimal format (without 0x prefix).	Ulong	4	H+4
4	ErrorCode	Error code for the operation. See Table: Error Code.	Enum	4	H+8
5	OperationMode	Operation mode code. See Table: Operation Mode Code.	Enum	4	H+12
6	TransactionID	This is the copy of Transaction ID provided to the command.	Ulong	4	H+16
7	ReadDataLength	For a Read operation, this is the actual number of bytes read from the I2C device. For a Write operation, this value is always zero.	Ulong	4	H+20
8	ReadData	For a Read operation, this is the data read from the device. For ASCII logs this field is displayed as a string of hexadecimal digits, with two digits per byte. The first byte retrieved from the I2C device is the first byte displayed and so on. The maximum size of this field is 256 bytes. When ReadDataLength is zero, this field will be empty.	HEXBYTE ARRAY	Y	H+24

Error Code
Binary	ASCII	Description
0	OK	I2C transaction is successful
1	IN_PROGRESS	I2C transaction is currently in progress
2	DATA_TRUNCATION	I2C transaction read data was truncated
3	BUS_BUSY	I2C bus is busy
4	NO_DEVICE_REPLY	No device replied to the I2C transaction request
5	BUS_ERROR	I2C bus error or bus arbitration lost
6	TIMEOUT	I2C transaction has timed out
7	UNKNOWN_FAILURE	I2C transaction has an unexplained failure
