Configuring the CAN/LIN Definition Data Settings
Data allocation ( [Byte order] )
Captured data using a big-endian ordering differs from those using a little-endian ordering although
the same data starting address (
[Start bit]
) and the same bit length (
[Bit length]
) are uses.
In the following figure, the shaded cells indicate the pieces of data to be captured when a bit length
of 10 and a data starting address (LSB position) of bit 16 are configured.
Big-endian ordering The MSB is configured at address 9.
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Byte 0 7 6 5 4 3 2 1 0
Byte 1 15 14 13 12 11 10 9 8
Byte 2 23 22 21 20 19 18 17 16
Byte 3 31 30 29 28 27 26 25 24
Little-endian ordering The MSB is configured at address 25.
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Byte 0 7 6 5 4 3 2 1 0
Byte 1 15 14 13 12 11 10 9 8

Byte 3 31 30 29 28 27 26 25 24
In the following figure, assuming that byte 0 and byte 1 have 16-bit data of FF and 00, respectively.
The following 16-bit data sets are captured:
Big-endian ordering (MSB first): FF00 (Data starting address: 8)
Little-endian ordering (LSB first): 00FF (Data starting address: 0)
