5.20.10.1.1 OUT Transactions
216
An Out transaction sends data to the debug device. It can occur only when the
following are true:
The sequence of the transaction is:
NOTE: A DATA_LEN_CNT value of 0 is valid in which case no data bytes would be
OWNER_CNT
1. Software sets the appropriate values in the following bits:
2. The debug port controller sends a token packet consisting of:
3. After sending the token packet, the debug port controller sends a data packet
• The debug port is enabled
• The debug software sets the GO_CNT bit
• The WRITE_READ#_CNT bit is set
consisting of:
— 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)
— SYNC
— TOKEN_PID_CNT field
— USB_ADDRESS_CNT field
— USB_ENDPOINT_CNT field
— 5-bit CRC field
— SYNC
— SEND_PID_CNT field
— The number of data bytes indicated in DATA_LEN_CNT from the DATA_BUFFER
— 16-bit CRC
