ENCODING OF THE SEGMENT
REGISTER (sreg) FIELD
The sreg field in certain instructions is a 2-bit field
allowing one of the CS, DS, ES or SS segment regis-
ters to be specified. The sreg field in other instruc-
tions is a 3-bit field, allowing the FS and GS segment
registers to be specified also.

ENCODING OF ADDRESS MODE
Except for special instructions, such as PUSH or
POP, where the addressing mode is pre-determined,
the addressing mode for the current instruction is
specified by addressing bytes following the primary
opcode. The primary addressing byte is the ‘‘mod
r/m’’ byte, and a second byte of addressing informa-
tion, the ‘‘s-i-b’’ (scale-index-base) byte, can be
specified.
The s-i-b byte (scale-index-base byte) is specified
when using 32-bit addressing mode and the ‘‘mod
r/m’’ byte has r/m
e
100 and mod
e
00, 01 or 10.
When the sib byte is present, the 32-bit addressing
mode is a function of the mod, ss, index, and base
fields.
The primary addressing byte, the ‘‘mod r/m’’ byte,
also contains three bits (shown as TTT in Figure 8.1)
sometimes used as an extension of the primary op-
code. The three bits, however, may also be used as
a register field (reg).
When calculating an effective address, either 16-bit
addressing or 32-bit addressing is used. 16-bit ad-
dressing uses 16-bit address components to calcu-
late the effective address while 32-bit addressing
uses 32-bit address components to calculate the ef-
fective address. When 16-bit addressing is used, the
‘‘mod r/m’’ byte is interpreted as a 16-bit addressing
mode specifier. When 32-bit addressing is used, the
‘‘mod r/m’’ byte is interpreted as a 32-bit addressing
mode specifier.
Tables on the following three pages define all en-
codings of all 16-bit addressing modes and 32-bit
addressing modes.
