NOTES:
AL = 8-bit accumulator
AX = 16-bit accumulator
CX = Count register
DS= Data segment
ES = Extra segment
Above/below refers to unsigned value.
Greater = more positive;
Less = less positive (more negative) signed values
if d = 1 then “to” reg; if d = 0 then “from” reg
if w = 1 then word instruction; if w = 0 then byte
instruction
if mod = 11 then r/m is treated as a REG field
if mod = 00 then DISP = O
, disp-low and disp-high
are absent
if mod = 01 then DISP = disp-low sign-extended
16-bits, disp-high is absent
if mod = 10 then DISP = disp-high:disp-low
if r/m = 000 then EA = (BX) + (SI) + DISP
if r/m = 001 then EA = (BX) + (DI) + DISP
if r/m = 010 then EA = (BP) + (SI) + DISP
if r/m = 011 then EA = (BP) + (DI) + DISP
if r/m = 100 then EA = (SI) + DISP
if r/m = 101 then EA = (DI) + DISP
if r/m = 110 then EA = (BP) + DISP
if r/m = 111 then EA = (BX) + DISP
DISP follows 2nd byte of instruction (before data
if required)
except if mod = 00 and r/m = 110 then
EA = disp-high: disp-low.
MOV CS, REG/MEMORY not allowed.
if s:w = 01 then 16-bits of immediate data form the operand.
if s:w. = 11 then an immediate data byte is sign extended
to form the 16-bit operand.
if v = 0 then “count” = 1; if v = 1 then “count” in (C
L
)
x = don't care
z is used for string primitives for comparison with ZF FLAG.

Instructions which reference the flag register file as a 16-bit
object use the symbol FLAGS to represent the file:
