Function RTURegisterXHCI

RTURegisterXHCI registers an XHCI USB host controller with RTUSB-32:

void RTURegisterXHCI(void * MemBase, void * DBBase, void * RRBase, BYTE IRQ);

Parameters

MemBase

Pointer to the host controller's memory mapped Capability Registers. This pointer must refer to the virtual address space and must allow read/write access.

DBBase

Pointer to the host controller's memory mapped Doorbell Registers. This pointer must refer to the virtual address space and must allow read/write access.

RRBase

Pointer to the host controller's memory mapped Run-time Registers. This pointer must refer to the virtual address space and must allow read/write access.

IRQ

Interrupt request number used by the host controller.

For PCI-based host controllers, the register address and IRQ value can be read from the PCI configuration space, as done by all demo programs in function FindUSBControllers in source file UsbInit.cpp.

For more information see function FindUSBControllers.

Initialization

Function RTURegisterCallback

Function RTURegisterEHCI
