Conditional Operations and Data Transfer: Some instructions belonging to this class can be
executed conditionally, as described earlier. The specified condition is valid only for the B field of
the instruction, and is not valid for data transfer instructions for which a parallel specification is
made. Examples are shown in figure 2.17.
DCT PADD X0,Y0,A0 MOVX.W @R4+,X0 MOVY.W A0,@R6+R9 ;
When condition is True
Before execution:
After execution:
X0=H'33333333, Y0=H'55555555, A0=H'123456789A,
