38-pin MICTOR connector
The MPS3 board provides one 1V8 38
‑
pin MICTOR connector. The connector supports P
‑
JTAG
processor debug to enable connection of DSTREAM, or a compatible third
‑
party debugger. The
connector also supports
Serial Wire Debug
(SWD) and 16
‑
bit trace.
The 38
‑
pin MICTOR connector connects to general
‑
purpose pins on the FPGA. The availability of
P
‑
JTAG, SWD, or 16
‑
bit trace depends on the design that you implement in the FPGA.
The following figure shows the 38
‑
pin MICTOR connector, J13.
