TI TLK10232 PHY

Hello, i need to view register states in 10G Ethernet PHY TLK10232 (TI). We have its JTAG located on the board and olimex ARM-USB-OCD-H JTAG adapter.

As I used openocd before i do something like this:

openocd -f interface -f cpu -f target.

What is interface is clear for me. But what should be cpu and target?

Or what other ways exists to view registers?
