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 }

1 2 ... 21 22 23 24 25 26 27 28 29 30 31 ... 123 124
