6300ESB I/O Controller Hub
An Out transaction sends data to the debug device. It may occur only when the
following are true:
The sequence of the transaction is listed below.
1. The debug port is enabled.
2. The debug software sets the GO_CNT bit.
3. The WRITE_READ#_CNT bit is set.
1. Software sets the appropriate values in these bits:
OWNER_CN
— USB_ADDRESS_CNF
— USB_ENDPOINT_CNF
— DATA_BUFFER[63:0]
— TOKEN_PID_CNT[7:0]
— SEND_PID_CNT[15:8]
— DATA_LEN_CNT
— WRITE_READ#_CNT (Note: This will always be 1 for OUT transactions.)
— GO_CNT (Note: This will always be 1 to initiate the transaction.)

Debug port in Mode 2. SOF
(and only SOF) is sent as
keepalive. Debug traffic is also
sent. Note that no other
normal traffic is sent out this
port, because the port is not
enabled.
Illegal. Host controller driver
should never put controller
into this state (enabled, not
running and not suspended).
Port is suspended. No debug
traffic sent.
Debug port in Mode 2. Debug
traffic is interspersed with
normal traffic.
Port is suspended. No debug
traffic sent.
