Figure 13-8: LIN frame with header and response
The data is transmitted in bytes using the UART byte-word interface without the parity
bit. Each byte consists of a start bit, 8 bits and a stop bit.
Figure 13-9: Structure of a byte field
Data bytes are transmitted LSB first.
The identifier byte consists of 6 bits for the frame identifier and two parity bits. This
combination is known as protected identifier.
Trigger
The R&S RTP can trigger on various parts of LIN frames. The data line must be con-
nected to an input channel, triggering on math and reference waveforms is not possi-
ble.
You can trigger on:
●
Frame start (synchronization field)
●
Specific identifier or identifier range
●
Data pattern in the message
●
Wake up signal
●
Checksum error (error in data), parity error (error in identifier)
