LRI64 to VCD frames
Response Frames are delimited by a Start of Frame (SOF) and an End of Frame (EOF) and
are implemented using a code violation mechanism. The LRI64 supports these in the one
subcarrier mode, at the fast data rate, only.
The VCD is ready to receive a response frame from the LRI64 before 320.9µs (t
having sent a command frame.
