DM8168 PCIe Reg address

Hi all,
 
I got confused when I look for the address of MSI_CAP reg(PCIe Message Signaled Interrupts Register, page 1728, DM8168 Technical Reference Manual 2012-5).
 
I do not know which PCIe reg set(app/local config/remote config/remote IO) it belongs to.
 
In C6670, I infer form this article http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/162874.aspx that MSI_CAP reg is local configuration space register, its offset is 0x50 and its addr is 0x21800000+0x1000+0x50=0x21801050.
 
But in DM8168 TRM, the offset of MSI_CAP is 0h, so I got confused.
 
Can anyone check this for me? Thanks in advance.
 
By the way, can ti point out register address more explicitly ?
