Figure A-7 Instruction Timing Summary (Continued)
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.

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.
