Address 0 is a legal fetch address.
The question is can I get away with not worrying about what is in the source
address register? What, for example, if it points to a non-address or to
something that happens to be fetch-protected. (Code is 64-bit FWIW, but I
doubt that matters, other than increasing the number of potential invalid
addresses.)
The example and explanation on page A-25 makes it clear that
the content of the even register (source address) are irrelevant
when the source length is zero.
