What exact sequence of the following machine addresses
of DD emulated by HHH causes DD to reach its own
final halt state at machine address [00002155]

[00002133] [00002134] [00002136] [00002137] [0000213c] [00002141] [00002144]
[00002147] [0000214b] [0000214f] [00002152] [00002154] [00002155]
(That HHH does not emulate all of this sequence is irrelevant: it causes
that anyway.)

When this sequence is required to conform to the
rules of the x86 language?

When any aspect of the execution or other semantics of those instructions
is discussed.
