Note: The 38-pin MICTOR interface is currently not supported. See the SmartLynq+ Module wiki page for the latest information.
The SmartLynq+ Module provides a MICTOR interface for high-speed trace capture. The interface supports 16-bit wide parallel trace and includes status and sync signals. The interface is implemented with a 38-pin, 0.64 mm pitch connector (TE P/N 5767044-1). The following figure shows the SmartLynq+ Module connected to the MICTOR interface on a target board.
