List of Known Bugs

The following is a list of the known bugs of the AS8202NF.

1. AS8202NF RX001 Receiver Bug

TTP requires a maximum level of error detection on the physical layer as well as on the semantic layer for a received

message. Among others the AS8202NF has a built-in ability to detect frames that are shorter or longer than

expected. This feature does not correctly work for all situations with MFM and Manchester encoding. Frames that are

too short or too long can appear to have the correct size. In this case the CRC check invalidates the frame. This bug

is reported as bug report AN120.
