XNET LIN Incomplete Frame, How are bits transmitted?

[NathanJD]

I have a LIN description that has some incomplete frames (i.e. the signals that make up the frame do not require all the bits in the frame).  For example, I have a 4 byte frame that has 5 signals but they only use up 28 bits of the frame.  How are the unused bits transmitted?  1's or 0's?

I've attached an image of the frame properties in the XNET Database Editor.

I don't have data to go off of on LIN, but in CAN it will be sent as 0s.

By default, XNET will fill the frame with zeroes in CAN, LIN, and Flexray. You can modify this behavior for certain session types by using the XNET Frame property: Default Payload. The XNET Hardware and Software manual has more details on this properties behavior.
