5.1.5 MICTOR 38 connector
The MPS2 and MPS2+ FPGA Prototyping Boards provides one 3V 38-pin MICTOR connector that
supports P-JTAG processor debug to enable connection of DSTREAM or a compatible third-party
debugger. The connector also supports 16-bit Trace and SWD.
The MICTOR 38 connector connects to generalpurpose pins on the FPGA. The availability of PJTAG,
SWD, and 16-bit Trace depends on the design which you implement in the FPGA. The MPS2 and
MPS2+ FPGA Prototyping Boards label this connector as PJTAG/TRACE.
The following figure shows the MICTOR 38 connector.
