USBOperational write
11.2 USB traffic generation
The USB states are reflected in the HostControllerFunctionalState (HCFS) field of the
HcControl register. The HCD is allowed to perform only USB state transitions shown in
Figure
USB traffic can be generated only when the ISP1362 USB Host Controller is under the
USBOperational state. Therefore, the HCD must set the ISP1362 USB HC in the
USBOperational state. This is done by setting the HCFS field of the HcControl register
before generating USB traffic.
A brief flow of the USB traffic generation is described as follows:
1. Reset the ISP1362 by using the RESET pin or the software reset.
2. Set the physical size of the ATL, interrupt, ISTL0 and ISTL1 buffers.
3. Write 32-bit hexadecimal value 8000 00FDh to the HcInterruptEnable register. This
4. Write 16-bit hexadecimal value 002Dh to the HcHardwareConfiguration register. This
5. Write 0500 0B02h to HcRhDescriptorA and 0000 0000h to HcRhDescriptorB.
6. Write 16-bit hexadecimal value 0680h to the HcControl register to set the ISP1362
7. Read the HcRhPortStatus[1] and HcRhPortStatus[2] registers. These registers
8. Connect a full-speed device to one of the downstream ports or use a 1.5 k resistor
