Address:
SOFIE — Start Of Frame Interrupt Enable
EOF2IE — The Second End of Frame Point Interrupt Enable
EOPIE — End of Packet Detect Interrupt Enable
TRANIE — Bus Signal Transition Detect Interrupt Enable

Read:
Write:
This read/write bit enables the Start Of Frame to generate a USB
interrupt when the SOFF bit becomes set. Reset clears this bit.
This read/write bit enables the Second End Of Frame to generate a
USB interrupt when the EOF2F bit becomes set. Reset clears this bit.
This read/write bit enables the USB to generate a interrupt request
when the EOPF bit becomes set. Reset clears the bit.
This read/write bit enables the Signal Transition to generate a USB
interrupt when the TRANF bit becomes set. Reset clears this bit.
1 = USB interrupt enabled for Start Of Frame
0 = USB interrupt disabled for Start Of Frame
1 = USB interrupt enabled for the Second End Of Frame Point
0 = USB interrupt disabled for the Second End Of Frame Point
1 = USB interrupt enabled for End-of-Packet sequence detection
0 = USB interrupt disabled for End-of-Packet sequence detection
1 = USB interrupt enabled for Bus Signal Transition
0 = USB interrupt disabled for Bus Signal Transition
