INSTRUCTION SET INTRODUCTION
MOTOROLA
Therefore, the instruction actually ignores what appears to be a duplicate destination and
logically ANDs the value in the X0 register with the bits in the A1 portion (bits 47-24) of
the A accumulator. The parallel move shown above can simultaneously write to either of
the other two portions of the A or the B accumulator without conflict. Avoid confusion by
explicitly stating A1 or B1 in the original instruction.
Optional data transfers may be specified with most logical instructions, allowing parallel
data movement over the XDB and YDB or over the GDB during a data ALU operation.
This parallel movement allows new data to be prefetched for use in subsequent instruc-
tions and allows results calculated in previous instructions to be stored. The following list
includes the logical instructions:
AND
Logical AND
ANDI
*
AND Immediate to Control Register
EOR
Logical Exclusive OR
LSL
Logical Shift Left
LSR
Logical Shift Right
NOT
Logical Complement
OR
Logical Inclusive OR
ORI
*
OR Immediate to Control Register
ROL
Rotate Left
ROR
Rotate Right
*These instructions do not allow parallel data moves.
