6.12 Security Block Register Descriptions
This section provides information on the registers associ-
ated with the Security Block (SB), including the Standard
GeodeLink Device (GLD) MSRs, the Security Block Spe-
cific MSRs (accessed via the RDMSR and WRMSR
instructions), and the Security Block Configuration/Control reg-
isters. Table 6-78 through Table 6-80 are register summary
tables that include reset values and page references where
the bit descriptions are provided.
The MSR address is derived from the perspective of the
CPU Core. See Section 4.1 "MSR Set" on page 45 for
more detail on MSR addressing.
