bus. If this bit is set, and then the chip will generate the interrupt. Cleared

by firmware when servicing the function resume interrupt.

FSUS

Function Suspend Flag:

Set by hardware when the function detects the suspend state on the USB

bus. If this bit is set, and then the chip will generate the interrupt. During the
