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
2
(see
Table
14.
) after having sent a response frame to the
VCD.
The LRI64 generates a Power On delay of t
POR
(see
Table 14.
) after being activated by the power-
ing field. After this delay, the LRI64 is ready to re-
ceive a command frame from the VCD.
In the ISO15693 standard, the SOF is used to de-
fine the data coding mode that the VCD is going to
use in the following command frame.
The SOF that is shown in
Figure 7.
selects the “1-
out-of-4” data coding mode. (The LRI64 does not
support the SOF for the “1-out-of-256” data coding
mode.)
The corresponding EOF sequence is shown in
Figure 8.
