8.2.7 Special-Purpose MOVE Instruction
The special-purpose MOVE instruction table indicates the number of clock periods needed
for the processor to fetch, calculate, and perform the special-purpose MOVE operation on
the control registers or specified effective address. 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.
