VCD to LRI64 frames
Request Frames are delimited by a Start of Frame (SOF) and an End of Frame (EOF) and
are implemented using a code violation mechanism. Unused options are reserved for future
use.
The LRI64 is ready to receive a new command frame from the VCD after a delay of t
Table
The LRI64 generates a Power On delay of t
powering field. After this delay, the LRI64 is ready to receive 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 command frame.
The SOF that is shown in
does not support the SOF for the “1-out-of-256” data coding mode.)
The corresponding EOF sequence is shown in
