CY7C67200 Interrupts Introduction EZ-OTG provides 128 interrupt vectors. The first 48 vectors EZ-OTG™ (CY7C67200) is Cypress Semiconductor’s first are hardware interrupts and the following 80 vectors are USB On-The-Go (OTG) host/peripheral controller. EZ-OTG is software interrupts. designed to easily interface to most high-performance CPUs to add USB host functionality. EZ-OTG has its own 16-bit RISC General Timers and Watchdog Timer processor to act as a coprocessor or operate in standalone E
