USB interrupt enable registers 1, 2

The USB interrupt enable registers are used to enable the USB function interrupt. Upon reset, all

USB interrupts except the USB suspend and USB resume interrupts are enabled.

The USB reset interrupt does not have an enable bit and is always in the enabled state.

Figures 2.6.12 shows the structures of USB interrupt enable registers 1 and 2.
