6.4.2 Logical Instructions
The logical instructions execute in one instruction cycle and perform all of the logical oper-
ations within the data ALU (except ANDI and ORI). They may affect all of the CCR bits
and, like the arithmetic instructions, are register based.
Logical instructions are the only instructions that allow apparent duplicate destinations,
such as:
A logical instruction uses only the MSP portion of the A and B registers (A1 and B1).
