Interrupts
A Functional Interrupt is generated by the logic in the USB device controller core to
indicate the occurrence of an event needing application intervention. The design of the
USB device core is such that events such as “link change” that would traditionally
trigger an interrupt through an interrupt status register, are instead delivered to an
‘Event buffer’

USB device core is such that events such as “link change” that would traditionally

‘Event buffer’
in host memory, together with an interrupt indicating this.
