Done1 Flag (Bit 2)
In host mode the Done 1 Flag bit is a read-only bit that
indicates if a host packet done interrupt occurs on Host 1. In
device mode this read-only bit indicates if any of the endpoint
interrupts occurs on Device 1. Firmware needs to determine
which endpoint interrupt occurred.

Reset1 Flag (Bit 1)
The Reset1 Flag bit is a read-only bit that indicates if a USB
Reset interrupt occurs on either Host/Device 1.

0: Interrupt did not trigger
Mailbox Out Flag (Bit 0)
The Mailbox Out Flag bit is a read-only bit that indicates if a
message is ready in the outgoing mailbox. This interrupt clears
when the external host reads from the HPI Mailbox register.
