15.4.1.10 Interrupt Enable Register (INT_ENB)
The Interrupt Enable Register contains enable bits for each of the interrupt sources within the USB
Module. Setting any of these bits enables the respective interrupt source in the INT_STAT register. This
register contains the value of 0x00 after a reset.
Figure 15-16 shows the INT_ENB register.
