Bit(s) Field
Type Default Description
2
RX2_MAP
RW
0
Map RX Port 2 to CSI-2 Port
0: CSI-2 Port 0
1: CSI-2 Port 1
It is recommended to disable forwarding for a
port before changing the port mapping
1
RX1_MAP
RW
0
Map RX Port 1 to CSI-2 Port
0: CSI-2 Port 0
1: CSI-2 Port 1
It is recommended to disable forwarding for a
port before changing the port mapping
0
RX0_MAP
RW
0
Map RX Port 0 to CSI-2 Port
0: CSI-2 Port 0
1: CSI-2 Port 1
It is recommended to disable forwarding for a
port before changing the port mapping
7
CSI_REPLICATE
RW
0
CSI Replicate Mode
When set to a 1, the CSI output from port 0 will
also be generated on CSI port 1. The same
output data is presented on both ports.

FWD_SYNC_AS_AV RW

AIL
Synchronized Forwarding As Available
During Synchronized Forwarding, each
forwarding engine will wait for video data to be
available from each enabled port, prior to
sending the video line. Setting this bit to a 1
will allow sending the next video line as it
becomes available. For example if RX Ports 0
and 1 are being forwarded, port 0 video line is
forwarded when it becomes available, rather
than waiting until both ports 0 and ports 1 have
video data available. This operation may
reduce the likelihood of buffer overflow errors
in some conditions. This bit will have no affect
in video line concatenation mode and only
affects video lines (long packets) rather than
synchronization packets.
This bit applies to both CSI output ports
5:4 CSI1_SYNC_FWD RW
0x0
Enable synchronized forwarding for CSI output
port 1 (See Synchronized Forwarding)
00: Synchronized forwarding disabled
01: Basic Synchronized forwarding enabled
10: Synchronous forwarding with line
interleaving
11: Synchronous forwarding with line
concatenation
Only one of CSI1_RR_FWD and
CSI1_SYNC_FWD must be enabled at a time.
3:2 CSI0_SYNC_FWD RW
0x0
Enable synchronized forwarding for CSI output
port 0 ( Synchronized Forwarding)
00: Synchronized forwarding disabled
01: Basic Synchronized forwarding enabled
10: Synchronous forwarding with line
interleaving
11: Synchronous forwarding with line
concatenation
Only one of CSI0_RR_FWD and
CSI0_SYNC_FWD must be enabled at a time.
