USB global interrupt flag register (UIF0)
There are many different events that generate a USB interrupt requiring a number of
registers to indicate the cause of the interrupt. To more efficiently identify the cause of
the interrupt, the USB global interrupt flag register (see
interrupt that occurred. Once the type of interrupt is identified, the associated interrupt
flag register may be read to determine the exact cause of the interrupt.

USB Reset flag
This bit is set when a USB Reset is detected on the D+ and D-
lines.
Note: A USB Reset does not reset the MCU nor the USB
module. Firmware should disable/enable the USB SIE using
the USEN bit in the UCTL register and initialize all USB related
registers as appropriate.
USB suspend mode flag
This bit is set when the SIE detects 3ms of no activity on the
bus and the clock to the SIE is also shut down to conserve
power. Clearing this bit turns the SIE clock on.
End of Packet flag
This bit is set when a valid End of Packet sequence is detected
on the D+ and D– line.
Resume flag
This bit is set when USB bus activity is detected while the
SUSPNDF Bit is set. When a Resume is detected, the
SUSPENDF bit must be cleared (if set) to turn the SIE clock on.
