Assembler Syntax:
ADD S,D (move syntax - see the MOVE in-
struction description.)
Description:
Add the low portion of the two specified operands and store the result in the low portion of the destination
operand D.
Input Operand(s) Precision: 32-bit integer.
Output Operand Precision: 32-bit integer.
CCR Condition Codes:
C - Set if carry is generated from 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.
Instruction Format: ADD S,D (move syntax - see the MOVE instruction description.)
Operation:
D.L + S.L → D.L (parallel data bus move)
