21.5.2
ED (endpoint descriptor) and TD (transfer descriptor) that define each transfer transaction of the
USB host controller must be placed such that each Dword is aligned on a longword boundary
(addresses 4n to 4n + 3) of the memory. Each descriptor must be aligned on a memory address
boundary prescribed by the OpenHCI specification Ver.1.0.
21.6
When modifying initial settings of the NOCP or OCPM bits in HcRhDescriptorA after reset, keep
the following in mind.
1. The initial values are NOCP=1 and OCPM=0, and the USB host controller does not detect
2. Making the settings in step 1 above will not change the settings in the OCI and OCIC bits in
3. Making the settings in step 1 above will set HcInterruptStatus.RHSC = 1 even if a port is not in

overcurrent. To use the overcurrent detection, set NOCP = 0 and OCPM = 1 simultaneously.
Modify these bits only once during USB host controller initialization. Do not modify them
more than once.
