12.1 USB states of the HC
The USB HC in the ISP1362 has four USB states: USBOperational, USBReset,
USBSuspend and USBResume. These states define the responsibilities of the HC
related to the USB signaling and bus states. These signals are visible to the HC
Driver (HCD), the software driver of the HC, by using the control registers of the
ISP1362 USB HC.
