gouping,
Mode 0 to Mode 4 refers to the lane setup per port. The PATH_CONFIG refers to how many lanes are available for use. For example, a value of 100 (Configuration 4) means that there are 4 lanes available. This would allow for a maximum of 4 ports (one lane each).
Table 2-17 on page 51 of SPRUGW1a has a pretty good explanation:

Guoping Lee,
You do not have the most recent SRIO UG. The latest version is SPRUGW1A http://www.ti.com/lit/ug/sprugw1a/sprugw1a.pdf
Thanks
