(12) Error processing and retry operation
1)
Error processing during transmission
When an error such as a CRC error is detected in the data transmitted by the ML60852, the host will not send
the ACK packet, and hence the ML60852 does not reset the transmit packet ready status, but waits while
retaining the current packet of data. The current packet of data is transmitted again when the next IN token is
received from the host.
Error processing during reception
When an error is detected in the data received over the USB bus, the ML60852 does not assert the interrupt
signal to the local MCU and will also not send any message to the host (leading to a timeout condition).
When the timeout condition is generated, the host recognizes that an error has occurred, and can take measures
such as re-transmitting the data, etc. In addition, since no interrupt request is generated, the local MCU will not
read the erroneous data.
