SOFIE — Start Of Fr ame Interrupt Enable

This read/write bit enables the Start Of Frame to generate a USB interrupt when the SOFF bit becomes set. Reset clears this bit.

1 = USB interrupt enabled for Start Of Frame

0 = USB interrupt disabled for Start Of Frame

EOF2IE — The Second End of Fr ame Point Interrupt Enable

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. 1 = USB interrupt enabled for the Second End Of Frame Point

0 = USB interrupt disabled for the Second End Of Frame Point

EOPIE — End of Packet De tect Interrupt Enable

This read/write bit enables the USB to generate a interrupt request when the EOPF bit becomes set. Reset clears the bit.

1 = USB interrupt enabled for End-of-Packet sequence detection 0 = USB interrupt disabled for End-of-Packet sequence detection

TRANIE — Bus Signal Transitio n Detect Interrupt Enable

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 Bus Signal Transition

0 = USB interrupt disabled for Bus Signal Transition
