• Manufacturer Part Number: dsp56000
• Description: 24-bit Digital Signal Processor Family Manual
• Manufacturer: Freescale Semiconductor, Inc

Operation:
Description: Take the ones complement of bits 47–24 of the destination operand D and
store the result back in bits 47–24 of the destination accumulator. This is a 24-bit opera-
tion. The remaining bits of D are not affected.
Example:
Explanation of Example: Prior to execution, the 56-bit A accumulator contains the
value $00:123456:789ABC. The NOT A instruction takes the ones complement of bits
47–24 of the A accumulator (A1) and stores the result back in the A1 register. The
remaining bits of the A accumulator are not affected.
Condition Codes:
S — Computed according to the definition in A.5 CONDITION CODE COMPUTATION
L — Set if data limiting has occurred during parallel move
N — Set if bit 47 of A or B result is set
Z — Set if bits 47-24 of A or B result are zero
V — Always cleared
