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
Use External V
0b — Use the internal OTG comparator.
1b — Use the external V

0b — Do not drive PSW_N to LOW, disabling V
1b — Drive PSW_N to LOW, enabling V

0b — Do not discharge V
1b — Discharge V
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.
