11.6. Isochronous Packet Receiving
The example of control flow for receiving Isochronous packet is shown below.
<Host> | <Device> |
START
Set necessary data to registers such as
Bridg and TSPIF.
Read Receive late occurred (INT30)
interrupt.
Set value to registers such as Bridge and
TSPIF(Note).
Receive Iso packet.
Store source packet in FIFO at Bridge.
Transmit source packet to CP LSI.
Receive processed source packet from CP LSI and store it in FIFO at TSPIF.
Receive Late evaluation
Receive Late | No |
| |
Yes |
|
Report Receive late occurred(INT30) |
|
interrupt(assert XINT). |
|
Discard source packet. |
|
Output source packet from the TSPIF port when the value of source packet header equals to the value of cycle timer.
