Universal Serial Bus Interfaces
between system software and host controller hardware. Information concerning the initialization of the
USB module is included in the following section; however, the full details of the EHCI specification are
beyond the scope of this document.
21.6.1
After initial power-on or host controller reset (hardware or through USBCMD[RST]), all of the operational
registers will be at their default values, as illustrated in Table 25. After a hardware reset, only the
operational registers not contained in the auxiliary power well will be at their default values.
In order to initialize the USB DR module, software should perform the following steps
At this point, the USB module is up and running and the port registers begin reporting device connects.
System software can enumerate a port through the reset process (where the port is in the enabled state). At
this point, the port is active with SOFs occurring down the enabled port enabled high-speed ports, but the

1. Set the controller mode to host mode. Optionally set USBMODE[SDIS] (streaming disable)
2. Optionally modify the BURSTSIZE register.
3. Program the PTS field of the PORTSC register if using a non-ULPI PHY.
4. Set CONTROL[USB_EN].
5. Write the appropriate value to the USBINTR register to enable the appropriate interrupts.
6. Write the base address of the periodic frame list to the PERIODICLIST BASE register. If there are
7. Write the USBCMD register to set the desired interrupt threshold, frame list size (if applicable) and
no work items in the periodic schedule, all elements of the periodic frame list should have their
T-Bits set.
