LRI64 PROTOCOL DESCRIPTION
The Transmission protocol defines the mecha-
nism to exchange instructions and data between
the VCD and the LRI64, in each direction. Based
on “VCD talks first”, the LRI64 does not start trans-
mitting unless it has received and properly decod-
ed an instruction sent by the VCD.
The protocol is based on an exchange of:
–
a Request from the VCD to the LRI64
–
a Response from the LRI64 to the VCD
Each Request and each Response are contained
in a Frame. The frame delimiters (SOF, EOF) are
described in the previous paragraphs.
Each Request (
Figure 16.
) consists of:
–
Request SOF (
Figure 7.
)
–
Request Flags (
Table 3.
to
Table 5.
)
–
Command Code
–
Parameters (depending on the Command)
–
Application Data
–
2-byte CRC (
Figure 15.
)
–
Request EOF (
Figure 8.
)
Each Response (
Figure 17.
) consists of:
–
Response SOF (
Figure 11.
)
–
Response Flags (
Table 6.
)
–
Parameters (depending on the Command)
–
Application Data
–
2-byte CRC (
Figure 15.
)
–
Response EOF (
Figure 12.
)
The number of bits transmitted in a frame is a mul-
tiple of eight, and thus always an integer number
of bytes.
Single-byte fields are transmitted Least Significant
Bit first.
Multiple-byte fields are transmitted Least Signifi-
cant Byte first, with each byte transmitted Least
Significant Bit first.
The setting of the flags indicates the presence of
any optional fields. When the flag is set, 1, the field
is present. When the flag is reset, 0, the field is ab-
sent.
