The USB OTG module has many conditions that can
be configured to cause an interrupt. All interrupt
sources use the same interrupt vector.
Figure 18-9 shows the interrupt logic for the USB
module. There are two layers of interrupt registers in
the USB module. The top level consists of overall USB
status interrupts; these are enabled and flagged in the
U1IE and U1IR registers, respectively. The second

level consists of USB error conditions, which are
enabled and flagged in the U1EIR and U1EIE registers.
An interrupt condition in any of these triggers a USB
Error Interrupt Flag (UERRIF) in the top level.
Interrupts may be used to trap routine events in a USB
transaction. Figure 18-10 provides some common
events within a USB frame and their corresponding
interrupts.
