P System RAM
The communication channel between the HC Driver and ISP1161’s USB 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.
The physical storage media of PTD data for the HC Driver is the microprocessor’s
system RAM. For ISP1161’s USB HC, it is the ISP1161’s internal FIFO buffer
RAM.
The HC Driver prepares PTD data in the microprocessor’s system RAM for transfer
to ISP1161’s HC internal FIFO buffer RAM.
Transfer PTD Data into HC’s FIFO Buffer RAM
When PTD data is ready in the microprocessor’s system RAM, the HC Driver must
transfer the PTD data from the microprocessor’s system RAM into ISP1161’s
internal FIFO buffer RAM.
HC Interprets PTD Data
The HC determines what USB transactions are required based on the PTD data
that have been transferred into the internal FIFO buffer RAM.
HC Performs USB Transactions via USB Bus Interface
The HC performs the USB transactions with the specified USB device endpoint
through the USB bus interface.
HC Informs HCD the USB Traffic Results
The USB transaction status and the feedback from the specified USB device
endpoint will be put back into the ISP1161’s HC internal FIFO buffer RAM in PTD
data format. The HC Driver can read back the PTD data from the internal FIFO
buffer RAM.
9.3 PTD data structure
The Philips Transfer Descriptor (PTD) data structure provides a communication
channel between the HC Driver and the ISP1161’s USB HC. PTD data contains
information required by the USB traffic. PTD data consists of a PTD followed by its
payload data, as shown in
