MOTOROLA
The following example calculates the instruction-cache-case execution time
for the specified instruction stream with two wait states (four-clock reads and
writes). The lines that are corrected for wait states are printed in boldface
type and are used to calculate the instruction execution time. References are
to the preceding rules.

tail are affected. Refer to preceding note.
For operation timings that include a data read (e.g., BFFF0 and TAS),
add the number of wait states to the CC time only. Neither the head
nor the tail are affected.
If the operation has more than one data read, add the total amount
of wait states for all reads to the CC time. Neither the head nor the
For operation timings that include a data write, the number of wait
states is added to the tail and the CC time. The head is not affected.
Refer to preceding note.
If there is more than one write in the operation, the tail is only
increased by the wait states for one write. The CC timing is increased
by the total amount of wait states for all writes. Refer to preceding
note.

The CC timing and tail of the MOVEM instruction are special
cases for both data reads and writes. Equations for both the CC
