5.7.2.5 ARITHMETIC/LOGIC INSTRUCTIONS. The arithmetic/logic instruction table indi-
cates the number of clock periods needed to perform the specified arithmetic/logical instruc-
tion using the specified addressing mode. Footnotes indicate when to account for the
appropriate EA times. The total number of clock cycles is outside the parentheses. The num-

X
= There is one bus cycle for byte and word operands and two bus cycles for long
operands. For long bus cycles, add two clocks to the tail and to the number of
cycles.
= Each bus cycle may take up to four clocks without increasing total execution time.
Cr
= Control registers USP, VBR, SFC, and DFC
n
= Number of registers to transfer
RL
= Register List
<= Maximum time (certain data or mode combinations may execute faster).
NOTES:
1. The MOVES instruction has an additional save step that other instructions do not have. To
calculate the total instruction time, calculate the save, the EA, and the operation execution
2. Timing is calculated with the CPU32+ in 16-bit mode.
