DESCRIPTION
Upstream Split Transaction Capability specifies the size of the buffer (in the
unit of ADQs) to store split completions for memory read. It applies to the
requesters on the secondary bus in addressing the completers on the primary
bus. The 0010h value shows that the buffer has 16 ADQs or 2K bytes
storage
Reset to 0010h
Upstream Split Transaction Commitment Limit indicates the cumulative
sequence size of the commitment limit in units of ADQs. This field can be
programmed to any value or equal to the content of the split capability field.
For example, if the limit is set to FFFFh, PI7C9X111SL is allowed to
forward all split requests of any size regardless of the amount of buffer space
available. The split transaction commitment limit is set to 0010h that is the
same value as the split transaction capability.
