transmitter automatically sends the last frame again after a parity error indication.
Optionally, this MLI event can activate a service request output.

23.1.3.4 Non-Acknowledge Error
A transmitter of an MLI module is able to detect an inoperable receiver by analyzing the
handshake signal TREADY. After TVALID has been asserted to 1, the transmitter
checks the receiver’s acknowledge (TREADY becoming 0). A Non-Acknowledge error
condition is detected by the transmitter when at the end of a frame transmission the
TREADY signal is still at high level (TREADY = 1 when TVALID becomes 0).
Figure 23-19 shows the Non-Acknowledge error case. In this case, the transmitter
automatically sends the last frame again. Optionally, this MLI event can activate a
service request output.
