Missing Differential Interface to FPGA

Topics about DSLogic as a logic analyzer
When I check the circuit diagram of DSLogic, there is a header pin "JP15". As per my understanding it is the differential interface. Its pins (FPGA_p0, FPGA_n0) are not connected to the FPGA. But I am able to find FPGA_p1 and n1.

Could anyone let me know the connection to the FPGA ?

I would like to know the use of the "Extension Differential Interface" mentioned in the wiki page - http://dreamsourcelab.com/wiki/index.ph ... Core_Board

Only the old DSLogic has the differential interface.
not DSLogic pro.
