VCD TO LRI64 FRAMES
Request Frames are delimited by a Start of Frame
(SOF) and an End of Frame (EOF) and are imple-
mented using a code violation mechanism. Un-
used options are reserved for future use.
The LRI64 is ready to receive a new command
frame from the VCD after a delay of t
14.) after having sent a response frame to the
VCD.
The LRI64 generates a Power On delay of t
(see
ing field. After this delay, the LRI64 is ready to re-
ceive a command frame from the VCD.

In ISO 15693 and ISO 18000-3 Mode 1 standards,
the SOF is used to define the data coding mode
that the VCD is going to use in the following com-
mand frame.
The SOF that is shown in
out-of-4” data coding mode. (The LRI64 does not
support the SOF for the “1-out-of-256” data coding
mode.)
