As a general rule, each value going into or coming out of a complex operation must be located at an even 32-bit word offset. This avoids problems in case a value needs to be passed to a 64-bit engine internal to the PKA module. The first consequence of this rule is that each of the vectors A...D must be located at an even offset. A second consequence is that when a vector consists of multiple components, alignment words may be necessary to ensure that each component starts at an even offset. As a reminder, the specification of each multi-component vector contains an [α] word wherever the insertion of an alignment word may be necessary.
