Note 1:

The STOP instruction disables all internal clocks.

Note 2:

The WAIT instruction takes a minimum of 16 clock

cycles to execute when an internal interrupt is

pending during the execution of the WAIT in-

struction.

A.9.1 Data ALU Operation Timing Summary

All Data ALU operations require only one instruction word. The actual number of words may be more than

one due to the parallel move specified with the Data ALU operation; this is indicated by the term "+mv"

which can be obtained from Figure A-9 . The number of cycles required for execution is also affected by

the parallel move operation, and the values for the term "+mv" are listed in Figure A-9. The values for the

term "+da" are listed in Figure A-8 for Data ALU operations when the IEEE mode is selected. In the Flush-

to-Zero mode, the term "+da" is always zero.
