32072G–11/2011
This bit is set when a USB “Start of Frame” PID (SOF) has been detected (every 1 ms). This triggers a USB interrupt if SOFE is
one. The FNUM field is updated. In High-speed mode, the MFNUM field is cleared.
This bit is cleared when the UDINTCLR.SOFC bit is written to one to acknowledge the interrupt.
This bit is set in High-speed mode when a USB “Micro Start of Frame” PID (SOF) has been detected (every 125 us). This
triggers a USB interrupt if MSOFE is one. The MFNUM field is updated. The FNUM field is unchanged.
This bit is cleared when the UDINTCLR.MSOFC bit is written to one to acknowledge the interrupt.
This bit is set when a USB “Suspend” idle bus state has been detected for 3 frame periods (J state for 3 ms). This triggers a
USB interrupt if SUSPE is one.
This bit is cleared when the UDINTCLR.SUSPC bit is written to one to acknowledge the interrupt.
This bit is cleared when the Wake-Up (WAKEUP) interrupt bit is set.
