Universal Serial Bus (USB) Controller
Register 4: USB Receive Interrupt Status (USBRXIS), offset 0x004
Important: This register is read-sensitive. See the register description for details.
USBRXIS is a 16-bit read-only register that indicates which of the interrupts for receive endpoints
1–15 are currently active.
Note: Bits relating to endpoints that have not been configured always return 0. Note also that all
active interrupts are cleared when this register is read.
