Intel 210200-002 manual ADC ADD with Carry ADC

ADC ADD WITH CARRY ADC

Encoding:

Memory or Register Operand with Register Operand:

10001 00 d w 1mod reg rIm 1

if d = 1 then LSRC = REG, RSRC = EA, DEST = REG else LSRC = EA, RSRC = REG, DEST = EA

Immediate Operand to Memory or Register Operand:

1100000 s w 1mod 0 1 0 rIm 1 data Idata if s:w=01!

LSRC = EA, RSRC = data, DEST = EA

Immediate Operand to Accumulator:

100 0 1 0 1 0 w 1 data 1 data if w=1 1

if w = 0 then LSRC = AL, RSRC = data, DEST = AL else LSRC = AX, RSRC = data, DEST = AX
