Internal Registers
SelfID Buffer Pointer Register
The SelfID Buffer Pointer register points to the 2 Kbyte aligned base address of the buffer in host memory where
the SelfID packets are stored during bus initialization. Bits 31:11 are read/write accessible.

SelfID Count Register
The SelfID Count register keeps a count of the number of times the SelfID process has occurred. The register
also flags any SelfID errors and maintains a count of the amount of SelfID data in the SelfID buffer.

Contains the 2 Kbyte aligned base address of the buffer in host
memory where received SelfID packets are stored.
Reserved.
When this bit is 1, an error was detected during the most recent
SelfID packet reception. The contents of the SelfID buffer are
undefined. This bit is cleared after a SelfID reception in which no
errors are detected. Note that an error can be a hardware error or
a host bus write error.
Reserved. Bits 30:24 return 0s when read.
The value in this field increments each time a bus reset is
detected. This field rolls over to 0 after reaching 255.
Reserved. Bits 15:11 return 0s when read.
This field indicates the number of quadlets that have been written
into the SelfID buffer for the current bits 23:16 (SelfIDGeneration
field). This includes the header quadlet and the SelfID data. This
field is cleared to 0 when the SelfID reception begins.
Reserved. Bits 1:0 return 0s when read.
