CPU Core Register Descriptions
5.5
All CPU Core registers are Model Specific Registers
(MSRs) and are accessed via the RDMSR and WRMSR
instructions.
Each module inside the processor is assigned a 256 regis-
ter section of the address space. The module responds to
any reads or writes in that range. Unused addresses within
a module’s address space are reserved, meaning the mod-
ule returns zeroes on a read and ignores writes. Addresses
that are outside all the module address spaces are invalid,

Table 5-13. CPU Core Specific MSRs Summary
meaning a RDMSR/WRMSR instruction attempting to use
the address generates a General Protection Fault.
The registers associated with the CPU Core are the Stan-
dard GeodeLink™ Device MSRs and CPU Core Specific
MSRs. Table 5-12 and Table 5-13 are register summary
tables that include reset values and page references where
the bit descriptions are provided. Note that the standard
GLD MSRs for the CPU Core start at 00002000h.
