instructions.
Some instructions access or use doubleword operands. These operands must be
placed in two consecutive register addresses where the first register must be an even
register. The even register contains the least significant part and the odd register con-
tains the most significant part. This ordering is reversed in comparison with how data is
organized in memory (where the most significant part would receive the lowest address)
and is intentional.
[i:j]
The programmer is responsible for placing these operands in properly aligned register
specified in the "Operands" section in the detailed description of each instruction. Fail-
result in an undefined behaviour.
