8.4 IMMEDIATE INSTRUCTION EXECUTION TIMES
The numbers of clock periods shown in Table 8-5 include the times to fetch immediate
operands, perform the operations, store the results, and read the next operation. 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 number of clock periods, the number of
read cycles, and the number of write cycles, respectively, must be added to those of the
effective address calculation where indicated by a plus sign (+).
In Table 8-5, the following notation applies:

Dn — Data register operand
An — Address register operand

MULS, MULU — The multiply algorithm requires 38+2n clocks where n is defined as:
DIVS, DIVU — The divide algorithm used by the MC68000 provides less than 10% difference
*** Only available effective address mode is data register direct.
Instruction
** The base time of six clock periods is increased to eight if the effective address mode is
+ Add effective address calculation time.
† Word or long only
* Indicates maximum basic value added to word effective address time
MULU: n = the number of ones in the <ea>
MULS: n=concatenate the <ea> with a zero as the LSB; n is the resultant number of 10
register direct or immediate (effective address time should also be added).
