Instruction Execution Timing
10.12 LEA, PEA, AND MOVEM EXECUTION TIMES
Table 10-20 indicates the number of clock cycles required for execution of the LEA, PEA,
and MOVEM instructions. The number of operand read and write cycles is shown in paren-
theses (r/w).

10.13 MULTIPRECISION INSTRUCTION EXECUTION TIMES
Table 10-21 indicates the number of clock cycles for execution of the multiprecision instruc-
tions. The number of clock cycles includes the time to fetch both operands, perform the
operations, and store the results. The number of read and write cycles is shown in paren-
theses (r/w).
10.14 STATUS REGISTER, MOVES, AND MISCELLANEOUS
Table 10-22, Table 10-23, and Table 10-24 indicate the number of clock cycles required for
execution of the status register, MOVES, and miscellaneous instructions. The number of
operand read and write cycles is shown in parentheses (r/w). Where indicated, the number
of clock cycles and r/w cycles must be added to those required for effective address calcu-
lation.
