Universal serial bus (USB) is an industry standard that defines cables, connectors, and serial communication protocol used in a bus for connection, communication, and power supply between electronic devices. PolarFire SoC FPGA device contains a USB On-The-Go (OTG) controller as part of the microprocessor subsystem (MSS). USB OTG controller provides a mechanism for the USB communication between the PolarFire SoC FPGA and external USB host/USB device/USB OTG protocol compliant devices.
