The USB traffic blocks are:
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 HCD must initialize
the ISP1161A 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 USBOperational 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 HCD must enter the USB transaction loop.
Prepare PTD data in
μ
P System RAM
The communication between the HCD and the ISP1161A HC is in the form of
Philips Transfer Descriptor (PTD) data. The PTD data provides USB traffic
information about the commands, status, and USB data packets.
