6.2 Editing the CAN Definition Data
6.2.4 Setting the data pattern
Here, the data pattern is set. Even if the data start position and data
length are the same, the data position (method of data acquisition)
varies depending on whether the data pattern is Motorola format or
Intel format.
The data pattern (method of data acquisition) is selected from the
following three systems:
Example : A data whose bit length is 10 bits and data start position (LSB position) is Bit 16.
<Motorola format> <Intel format>
7 6 5 4 3 2 1 0
15 14 13 12 11 10 9 8

The position of Bit 9 is the MSB
(most significant bit) position. The position of Bit 25 is the MSB
(most significant bit) position.
U/L (Motorola)
Data is extracted according to Motorola format.
L/U (Motorola)
Data is extracted according to Motorola format,
then the high-byte and low-byte positions are
switched. This setting is effective when the data
length is from 9 to 16 bits. When the data length
is 8 bits or shorter, this setting function is the
same way as U/L (Motorola).
L/U (Intel)
Data is extracted according to Intel format.
