The bits in this register enable interrupts and RXCMDs to be sent when the corresponding
bits in the USB Interrupt Status register change from logic 0 to logic 1. By default, all
transitions are enabled.
Description

DM Pull Down: Enables the 15 k pull-down resistor on DM.
0b — Pull-down resistor is not connected to DM.
1b — Pull-down resistor is connected to DM.
DP Pull Down: Enables the 15 k pull-down resistor on DP.
0b — Pull-down resistor is not connected to DP.
1b — Pull-down resistor is connected to DP.
