• 2 - SOFE - Start Of Frame Interrupt Enable Bit
Set to enable the SOFI interrupt.
Clear to disable the SOFI interrupt.
• 1 - Reserved
The value read from this bits is always 0. Do not set this bit
• 0 - SUSPE - Suspend Interrupt Enable Bit
Set to enable the SUSPI interrupt.
Clear to disable the SUSPI interrupt.
• 7 - ADDEN - Address Enable Bit
Set to activate the UADD (USB address).
Cleared by hardware. Clearing by software has no effect.
