5.7.3.8 SINGLE OPERAND INSTRUCTIONS. The single operand instruction table

indicates the number of clock periods needed for the processor to perform the specified

operation using the specified addressing mode. The total number of clock cycles is

outside the parentheses. The numbers inside parentheses (r/p/w) are included in the total

clock cycle number. All timing data assumes two-clock reads and writes.

operands. For long-word bus cycles, add two clocks to the tail and to the number of

cycles.
