GeodeLink™ Control Processor Register Descriptions

All GeodeLink Control Processor registers are Model Spe-
cific Registers (MSRs) and are accessed via the RDMSR
and WRMSR instructions.

The registers associated with the GLCP are the Standard
GeodeLink™ Device (GLD) MSRs and GLCP Specific
MSRs. Table 6-85 and Table 6-86 are register summary

tables that include reset values and page references where
the bit descriptions are provided.

Note:

The MSR address is derived from the perspective
of the CPU Core. See Section 4.1 "MSR Set" on
page 45 f
or more details on MSR addressing.
