• Storing Data from the Leftmost Byte
Set bits 12 to 15 of C+1 to 0 hex.
• Storing Data from the Rightmost Byte
Set bits 12 to 15 of C+1 to 8 hex.
Precaution
Be sure that the order of bytes in the source data
matches the order in the explicit message's
frame (order of data in the line). For example,
when the service data is in 2-byte or 4-byte units,
the order of data in the frame is leftmost to
rightmost order in 2-digit pairs, as shown in the
following diagram.
The following diagrams show how data is stored in the data areas when the service data is in 2-byte or
4-byte units.
1) Data in 2-byte Units
• Storing Data from the Leftmost Byte (Bits
12 to 15 of C = 0 hex)
Example: Storing the value 1234 hex in
S+5
• Storing Data from the Rightmost Byte (Bits
12 to 15 of C = 8 hex)
Example: Storing the value 1234 hex in
S+5
2) Data in 4-byte Units
• Storing Data from the Leftmost Byte (Bits
12 to 15 of C = 0 hex)
Example: Storing the value 12345678 hex
in S+5 and S+6
