7.9 JMP, JSR, LEA, PEA, AND MOVEM INSTRUCTION
Table 7-11 lists the timing data for the jump (JMP), jump to subroutine (JSR), load
effective address (LEA), push effective address (PEA), and move multiple registers
(MOVEM) instructions. The total number of clock periods, the number of read cycles, and
the number of write cycles are shown in the previously described format.

7.10 MULTIPRECISION INSTRUCTION EXECUTION TIMES
Table 7-12 lists the timing data for multiprecision instructions. The numbers of clock
periods include the times to fetch both operands, perform the operations, store the results,
and read the next instructions. The total number of clock periods, the number of read
cycles, and the number of write cycles are shown in the previously described format.
The following notation applies in Table 7-12:
7-8
*The size of the index register (Xn) does not affect the instruction's execution time.
n is the number of registers to move.
Dn — Data register operand
M — Memory operand
