OUT 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
— GO_CNT

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.
