8.2 ENDPOINT INTERRUPT REGISTER (EIR)
The endpoint interrupt register lets the MCU knows what endpoint generates the interrupt. The source of an
interrupt could be various, but, when an interrupt is detected, the endpoint status register should be checked to
identify if it’s related to specific endpoint. Clearing the bits can be accomplished by writing “1” to the bit position
where the interrupt is detected.
