† XC 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.
