8.2.11 Single-Operand Instructions
The single-operand instructions table indicates the number of clock periods needed for the
processor to perform the specified operation on the given addressing mode. Footnotes
indicate when it is necessary to add another table entry to calculate the total effective
execution time for the instruction. The total number of clock cycles is outside the
parentheses; the number of read, prefetch, and write cycles is given inside the
parentheses as (r/p/w). These cycles are included in the total clock cycle number.
