Functional description
50
The formats "INTEL Standard", "MOTOROLA Forward"
and "MOTOROLA Backward" use the following "saw
tooth" data bit numbering system:
Byte 0 (from the CAN controller)
Bit 7
6
5
Byte 1
15
14
13
The formats "INTEL Sequential" and "MOTOROLA
Sequential" use the following sequential data bit
numbering system. It corresponds to the sequence in
which the bits are received by the CAN bus:
Byte 0 (from the CAN controller)
Bit 0
1
2
Byte 1
0
1
2
6.6.1.1 INTEL Standard format
For signals in "INTEL Standard" format, the stated "Start
bit" is the position of the least significant bit ("lsb") of the
measured value, and the bit significance increases to the
left, numbering from the start bit, as shown in the exam
ple below.
The following applies for data reception in the CAN
decoder: If the data type is signed, this is always
assumed in the "msb" and is filled with 1 when right-
shifting to the intermediate value. If the "BitSequence" or
"ModeBitSequence" element has the value "1", this
