An IN transaction receives data from the debug device. It can occur only when the
following are true:
The sequence of the transaction is:
IN Transactions
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 waits for a response from
4. If valid packet was received from the device that was one byte in length (indicating
5. If valid packet was received from the device that was more than one byte in length
6. If no valid packet is received, then the debug port controller:
• The debug port is enabled
• The debug software sets the GO_CNT bit
• The WRITE_READ#_CNT bit is reset
the debug device.
If a response is received:
it was a handshake packet), then the debug port controller:
(indicating it was a data packet), then the debug port controller:
— USB_ADDRESS_CNF
— USB_ENDPOINT_CNF
— TOKEN_PID_CNT[7:0]
— DATA_LEN_CNT
— WRITE_READ#_CNT (note: this will always be 0 for IN 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.
— The received PID is placed into the RECEIVED_PID_STS field
— Any subsequent bytes are placed into the DATA_BUFFER
— The DATA_LEN_CNT field is updated to show the number of bytes that were
— Resets the ERROR_GOOD#_STS bit
— Sets the DONE_STS bit
— Transmits an ACK handshake packet
— Resets the ERROR_GOOD#_STS bit
— Sets the DONE_STS bit
— Sets the EXCEPTION_STS field to 001b
— Sets the ERROR_GOOD#_STS bit
— Sets the DONE_STS bit.
