Interrupt bits are reset by writing a 1 to the specified bits. Writing 0 has no
effect.

Reserved, should be cleared.
Device configuration change interrupt. Set when a device configuration change has been
received. The USB standard device requests SET_CONFIGURATION and SET_INTERFACE
generate a DEV_CFG interrupt. Any IN or OUT packets to the active endpoints cause a NAK
response to the host while this bit is set in order to allow the user to initialize the endpoints’
FIFO’s. Note that if one of these requests is done repeatedly and therefore the registers don’t
change, a DEV_CFG interrupt is still generated. If debug mode is enabled, a change in FAR also
generates an interrupt.
