The WG has identified a contradiction in the CSI-2 Specification for descriptions of RAW6 and RAW7 data
1
format (Section 11.4.1 and Section 11.4.2) in the CSI-2 Specification since v1.0 (including CSI-2 v1.01, 2
CSI-2 v1.1, CSI-2 v1.2, CSI-2 v1.3, CSI-2 v2.0, and CSI-2 v2.1). 3
The RAW6 and RAW7 data format descriptions describe the format as including LS/LE synchronization codes. 4
The WG has confirmed that line synchronization packets are optional, and the correction is to remove the second 5
sentence of each paragraph for RAW6 and RAW7 in order to remove the contradicting statements. 6

Correction
1 152 172 Editorial or Technical: Technical
Location: Line 1719-1720
Correction: Remove sentence “Each line is separated by line start / end
synchronization codes.”
Reason: This sentence contradicts the specification statement that line
synchronization packets (LS/LE short packets) are optional. For
reference, see Section 9.8.2 Line Synchronization Packet, line
1165 stating “Line synchronization packets are optional on a per-
image-frame basis.”
Technical Impact: Hardware implementations transmitting the additional
LS/LE short packets in conjunction with this data type may wish to
make them optional in the future for users not desiring them. Any
CSI-2 verification IP reporting a non-conformance error when
LS/LE short packets are not transmitted in conjunction with this
data type must be changed in order to no longer report this error.
2 153 173 Editorial or Technical: Technical
Location: Line 1728-1729
Correction: Remove sentence “Each line is separated by line start / end
synchronization codes.”
Reason: This sentence contradicts the specification statement that line
synchronization packets (LS/LE short packets) are optional. For
reference, see Section 9.8.2 Line Synchronization Packet, line
1165 stating “Line synchronization packets are optional on a per-
image-frame basis.”
Technical Impact: Hardware implementations transmitting the additional
LS/LE short packets in conjunction with this data type may wish to
make them optional in the future for users not desiring them. Any
CSI-2 verification IP reporting a non-conformance error when
LS/LE short packets are not transmitted in conjunction with this
data type must be changed in order to no longer report this error.
