Note: A DATA_LEN_CNT value of zero is valid in which case no data bytes would be included
6300ESB ICH
in the packet.
An IN transaction receives data from the debug device. It may occur only when the
following are true:
The sequence of the transaction is:
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
4. After sending the data packet, the controller waits for a handshake response from
1. The debug port is enabled
2. The debug software sets the GO_CNT bit
3. The WRITE_READ#_CNT bit is reset
1. Software sets the appropriate values in the following bits:
2. The debug port controller sends a token packet consisting of:
•
•
consisting of
the debug device.
When a handshake is received, the debug port controller:
When no handshake PID is received, the debug port controller:
b. TOKEN_PID_CNT field
d. USB_ENDPOINT_CNT field
b. SEND_PID_CNT field
d. 16-bit CRC
b. TOKEN_PID_CNT field
a. SYNC
c. USB_ADDRESS_CNT field
e. 5-bit CRC field
a. SYNC
c. The number of data bytes indicated in DATA_LEN_CNT from the DATA_BUFFER
— 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.)
a. SYNC
a. Places the received PID in the RECEIVED_PID_STS field
b. Resets the ERROR_GOOD#_STS bit
c. Sets the DONE_STS bit
a. Sets the EXCEPTION_STS field to 001b
b. Sets the ERROR_GOOD#_STS bit
c. Sets the DONE_STS bit
