18.5.4 USB Receive Interrupt Status Register (USBRXIS), offset 0x004

NOTE: Use caution when reading this register. Performing a read may change bit status.
The USB receive interrupt status 16-bit read-only register (USBRXIS) indicates which interrupts are
currently active for receive endpoints 1–15.
Note: Bits relating to endpoints that have not been configured always return 0. All active interrupts are
cleared when this register is read.
Mode(s): OTG A or Host
