is one cycle if XAAU contention occurs and zero cycles otherwise. XAAU contention occurs frequently for these instruc-
tion types and can only be avoided by use of the cache.
For this transfer, the postincrement options
*rME
and
*rME––
are not available
for double-word loads.
§ The – (40-bit subtraction) operation is encoded as
aDE=aSE+IM16
with the IM16 value negated.
For conditional branch instructions, the execution time is two cycles if the branch is not taken.
The instruction performs the same function whether or not
near
(optional) is included.
§§ Not including the N instructions.
