NOTES:
MOTOROLA
“n” is the number of registers being moved.
For all FPU operations, if the external operand format is byte, word, or long, add three cycles to the execution time.
*For all FPU operations except FMOVEM, if the external operand format is extended precision, add two cycles to the
execution time.
Add 2(1/0) cycles to the (bd,An,Xi*SF) time for a memory indirect address.
Add 1(0/0) cycle if the <ea> specifies a double precision immediate operand.
