9.1 OPERAND EFFECTIVE ADDRESS CALCULATION TIMES
Table 9-1 lists the numbers of clock periods required to compute the effective addresses
for instructions. The totals include fetching any extension words, computing the address,
and fetching the memory operand. The total number of clock periods, the number of read
cycles, and the number of write cycles (zero for all effective address calculations) are
shown in the previously described format.
*The size of the index register (Xn) does not affect execution time.
9.2 MOVE INSTRUCTION EXECUTION TIMES
Tables 9-2, 9-3, 9-4, and 9-5 list the numbers of clock periods for the move instructions.
The totals include instruction fetch, operand reads, and operand writes. The total number
of clock periods, the number of read cycles, and the number of write cycles are shown in
the previously described format.
