Register 6: USB Receive Interrupt Enable (USBRXIE), offset 0x008
USBRXIE is a 16-bit register that provides interrupt enable bits for the interrupts in USBRXIS. When
a bit in USBRXIE is set to 1, the USB interrupt to the processor is asserted when the corresponding
interrupt bit in the USBRXIS register is set. When a bit is cleared to 0, the interrupt in USBRXIS is
still set but the USB interrupt to the processor is not asserted. On reset, the bits corresponding to
receive endpoints 1-3 are set to 1, while the remaining bits are set to 0.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
