USB 2.0 OTG dual-role controller
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
USB 2.0 dual-role device/host controller with OTG HNP/SRP, ADP and role switching driven by ID pin or Type-C.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
