8.1.2.4
The eee field (bits [5:3]) is used to select the control, debug, and test registers in the MOV instructions. The type of register
and base registers selected by the eee field are listed in Table 8-7. The values shown in Table 8-7 are the only valid encod-
ings for the eee bits.
8.1.3
The mod and r/m fields within the mod r/m byte select the type of memory addressing to be used. Some instructions use a
fixed addressing mode (e.g., PUSH or POP) and therefore, these fields are not present. Table 8-8 lists the addressing method
when 16-bit addressing is used and a mod r/m byte is present. Some mod r/m field encodings are dependent on the w field
and are shown in Table 8-9.
