5.1
The GeodeLink Interface Unit (GLIU) registers are Model
Specific Registers (MSRs) and are accessed through the
RDMSR and WRMSR 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.
The MSRs are split into the following groups:
• Standard GeodeLink Device MSRs
MSR Address
