DIVERSE INTEGRATION LOGIC REGISTER DESCRIPTIONS

All registers associated with Diverse Integration Logic

(DIVIL) are MSRs:

• Standard GeodeLink Device MSRs

• DIVIL Specific MSRs

The MSRs are accessed via the RDMSR and WRMSR pro-

cessor instructions. The MSR address is derived from the

perspective of the CPU Core. See Section 3.2 "CS5535

MSR Addressing" on page 53 for more details on MSR

addressing.

All MSRs are 64 bits, however, some DIVIL MSRs are

called out as 32 bits. The DIVIL (MDD) treats writes to the

upper 32 bits (i.e., bits [63:32]) of the 32-bit MSRs as don’t

cares and always returns 0 on these bits.

The Standard GeodeLink Device MSRs are summarized in

Table 5-17 and the DIVIL Specific MSRs are summarized

in Table 5-18. The reference column in the tables point to

the page where the register maps and bit descriptions are

listed. Some notations in the reference column also point to

other chapters. These MSRs are physically located in the

DIVIL, but the descriptions are documented with the asso-

ciated module and are listed here only for completeness.
