INSTRUCTION DESCRIPTIONS
MOTOROLA INSTRUCTION SET DETAILS A - 159
Explanation of Example: Prior to execution, the 56-bit A accumulator contains the
value $FF:FFFFFF:FFFFFF, and the 24-bit X0 register contains the value $234567. The
execution of the MOVE X0,A1 instruction moves the 24-bit value in the X0 register into
the 24-bit A1 register without automatic sign extension and without automatic zeroing.
Condition Codes:
S — Computed according to the definition in A.5 CONDITION CODE COMPUTATION
L — Set if data limiting has occurred during parallel move.
