8.2 MOVE INSTRUCTION EXECUTION TIMES
Tables 8-2 and 8-3 list the numbers of clock periods for the move instructions. The totals
include instruction fetch, operand reads, and operand writes. The total number of clock
periods, the number of read cycles, and the number of write cycles are shown in the
previously described format.
*The size of the index register (Xn) does not affect execution time.
