RECFBD[9:0]: FBD Error Log  
.This register contains FBD frame data received that matches the logged frame error.  
Captures {BC} from frame N and A from frame N+1 where  
[11:8] = A[n+1]  
[7:4] = C[n] slot  
[3:0] = B[n] slot  
The contents of this register are only valid when one of the errors that set this register  
is logged in the FERR register. The contents of this register should not change until the  
error indication is cleared from the FERR register.

PERSONALITY BYTES Loaded From the SPD  
These bytes allow for AMB implementation specific settings to be loaded in an  
architected way by BIOS without BIOS being aware of specific AMB requirements. Each  
AMB vendor defines how these bytes should be loaded for the specific DIMM being built.  
The values to be loaded into these bytes are stored in the SPD EEPROM on the DIMM.  
The first six bytes are required to be loaded into the AMB via SMBus before link  
initialization to allow for configuration information needed for robust link operation.  
The remaining 8 bytes must be loaded before the FBD begins normal operation.  
Usage of these bytes can include  
• DDR electrical parameters to optimize performance on a given DIMM  
— For example, DLL delay settings, various I/O driver slew settings,  
• Enable/disable of various optimizations that may have been included in the design  
but can be turned off if they are not needed on this DIMM or they have  
unanticipated side effects - for example, power save modes, alternate clock  
recovery algorithms, and so forth.
