In Table 7-5, the following notation applies:
7.4 IMMEDIATE INSTRUCTION EXECUTION TIMES
The numbers of clock periods shown in Table 7-6 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
7-4
An — Address register operand
Dn — Data register operand
ea — An operand specified by an effective address
M
— Memory effective address operand

MULS, MULU — The multiply algorithm requires 42+2n clocks where n is defined as:
DIVS, DIVU — The divide algorithm used by the MC68008 provides less than 10% difference
*** Only available effective address mode is data register direct.
Instruction
** The base time of 10 clock periods is increased to 12 if the effective address mode is
+ Add effective address calculation time.
* Indicates maximum base value added to word effective address time
register direct or immediate (effective address time should also be added).

Table 7-5. Standard Instruction Execution Times
between the best- and worst-case timings.
MULS: n = tag the <ea> with a zero as the MSB; n is the resultant number of 10
or 01 patterns in the 17-bit source; i.e., worst case happens when the source
is $5555.
MULU: n = the number of ones in the <ea>
