32
8.5 Frame Template Multi-byte Field Byte Order
Attribute
By default, for fields up to 32 bits, the parser uses the Little Endian (LSB -> MSB) byte order.
For example, if a 32-bit field has the value 0xAABBCCDD, it is written into the byte stream as:
DD CC BB AA
Example
Frame MY_TEMPLATE
{
Field_16 : 16 = 0xEEFF
Field_32 : 32 = 0xAABBCCDD
}
The byte stream based on this template is:
FF EE DD CC BB AA
8.5.1 Big Endian Byte Order
You can require that all template fields have the Big Endian (MSB -> LSB) byte order. Adding
(MSB) after the ancestor list in the template declaration instructs the script parser to choose the
MSB -> LSB byte order.
Example
Frame MY_TEMPLATE (MSB)
{
Field_16 : 16 = 0xEEFF
Field_32 : 32 = 0xAABBCCDD
}
The byte stream based on this template is:
EE FF AA BB CC DD
Note: This attribute is needed only for assignments in which numeric literals (such as
0xAABBCCDD or 12323344 ) are used.
