5.17.10.1.1OUT Transactions
An Out transaction sends data to the debug device. It can occur only when the following are true:
The sequence of the transaction is:
1. Software sets the appropriate values in the following bits:
OWNER_CNT
•
•
•
The debug port is enabled
The debug software sets the GO_CNT bit
The WRITE_READ#_CNT bit is set
— 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 is not being used.
Normal operation.
Debug port is not being used.
Normal operation.
Debug port in Mode 1. SYNC
keepalives sent plus debug traffic
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.
