→
D.L (parallel data bus move)
Assembler Syntax:
NEG D
( See the MOVE instruction description.)
Description:
The low portion of the destination operand is subtracted from zero. The result is stored in the low portion
of D. This instruction is preferable to using the SUB instruction since it is not necessary to zero an input
operand.
Input Operand(s) Precision: 32-bit integer.
Output Operand Precision: 32-bit integer.
CCR Condition Codes:
C
- Set if a borrow is generated from the MSB of the result. Cleared otherwise.
V
- Set if result overflows. Cleared otherwise.
Z
- Set if result is zero. Cleared otherwise.
N
- Set if result is negative. Cleared otherwise.
I
- Not affected.
LR
- Not affected.
–
R
- Not affected.
A
- Not affected.
ER Status Bits: Not affected.
IER Flags: Not affected.
