8.2.5 Specifying Byte Order in Field Definitions
You can specify the byte order for integer fields (length <= 32 bits) using the Byte Order field
attribute. The Byte Order field attribute indicates how numeric values are assigned to integer
fields. By default, the byte order for integer fields is Big Endian: MSB->LSB. For example, the
integer value 0xAABBCCDD is assigned as the {AA BB CC DD} byte stream.
Example
# Specify byte order for some fields of a template.
Frame
Mixed
{
F1 :
16
F2 :
32
(MSB)
F3 :
16
(MSB) =
0xAABB
F4 :
32
=
0xAABBCCDD
}
# Template with the same field layout as the template above
Frame
MSBMixed (MSB)
{
F1 :
16
(LSB)
F2 :
32
F3 :
16
=
0xAABB
F4 :
32
(LSB) =
0xAABBCCDD
}
8.2.6 Using Byte Stream Literals in Field Assignments
You can specify the byte order explicitly using byte stream literals:
Example
Field_32 :
32
=
{
AA BB CC DD
}
