A simplistic flow diagram showing when and how to generate USB traffic is shown in
Figure 24
. For greater accuracy, refer to both the Universal Serial Bus Specification
Revision 1.1about the protocol and ISP1161 USB HC’s register usage.
Reset
This includes hardware reset by pin RESET and software reset by the
HcSoftwareReset command (A9H). The reset function will clear all the HC’s
internal control registers to their reset status. After reset, the HC Driver must
initialize the ISP1161 USB HC by setting some registers.
Initialize HC
It includes:
Setting the physical size for the HC’s internal FIFO buffer RAM by setting the
HcITLBufferLength register (2AH - Read, AAH - Write) and the
HcATLBufferLength register (2BH - Read, ABH - Write)
Setting the HcHardwareConfiguration register according to requirements
Clearing interrupt events, if required
Enabling interrupt events, if required
Setting the HcFmInterval register (0DH - Read, 8DH - Write)
Setting the HC’s root hub registers
Setting the HcControl register to move the HC into USB Operational state

Entry
The normal entry point. The microprocessor returns to this point when there are
HC requests.
Need USB Traffic
USB devices need the HC to generate USB traffic when they have USB traffic
requests such as:
Connecting to or disconnecting from the downstream ports
Issuing the Resume signal to the HC
To generate USB traffic, the HC Driver must enter the USB transaction loop.
