What is the interrupt endpoint?
Answer With the exception of the HT82K68A/E, the HT82XX Interrupt Endpoints, each have an 8 X 8 FIFO buffer which can support a USB Interrupt transfer transmission. The HID class Keyboard or mouse data can utilise this Interrupt Endpoint to transmit data to the PC. For the details regarding this Interrupt transfer please consult the USB 1.1 specification.
