9.9 JMP, JSR, LEA, PEA, AND MOVEM INSTRUCTION
Table 9-16 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.
