USB Interrupt Flag Registers 0 and 1 (USBIFR0, USBIFR1)

USBIFR0 and USBIFR1 have interrupt flags which generate interrupts from the USB module to
the slave CPU.
The USB module supports four interrupt sources: USBIA, USBIB, USBIC, and USBID. USBIA is
specific to a setup interrupt. USBIB and USBIC can be used for either transfer normal completion
interrupts or transfer abnormal completion interrupts. USBID can be used for other interrupts such
as transfer normal completion interrupts, transfer abnormal completion interrupts, RFU/FIFO read
request interrupts, bus reset interrupts, SOF interrupts, suspend OUT interrupts, suspend IN
interrupts, SetConfiguration command detection interrupts, and SetInterface command detection
interrupts.
USBIFR0 and USBIFR1 are initialized to H'00 by a system reset or function software reset (see
section 18.3.16, USB Control Registers 0 and 1 (USBCR0, USBCR1)).
