Summary of Multiply, Divide and Decimal-adjust Instructions
Note:
1. A shaded cell denotes an instruction in the C51 Architecture.
MultiplyMUL AB(B:A)
← (A)×(B)
MUL <dest>, <src>extended dest opnd
← dest opnd × src opnd
DivideDIV AB(A)
← Quotient ((A) (B))
(B)
← Remainder ((A) (B))
DivideDIV <dest>, <src>ext. dest opnd high
← Quotient (dest opnd src opnd)
ext. dest opnd low
← Remainder (dest opnd src opnd)
Decimal-adjust ACCDA AIF [[(A)3:0 > 9] ∨ [(AC) = 1]]
for Addition (BCD)
THEN (A)3:0 ← (A)3:0 + 6 !affects CY;
IF [[(A)7:4 > 9] ∨ [(CY) = 1]]
THEN (A)7:4 ← (A)7:4 + 6
