• 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.
See Section 22.7, page 269 for more details.
• 6-0 - UADD6:0 - USB Address Bits
Load by software to configure the device address.
.
• 7-3 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 2-0 - FNUM10:8 - Frame Number Upper Value
Set by hardware. These bits are the 3 MSB of the 11-bits Frame Number information. They are
