Enable best-effort forwarding for CSI output
port 1.
When this mode is enabled, no attempt is
made to synchronize the video traffic. When
multiple sources have data available to
forward, the data will tend to be forwarded in a
round-robin fashion.
0: Round robin forwarding disabled
1: Round robin forwarding enabled
Only one of CSI1_RR_FWD and
CSI1_SYNC_FWD must be enabled at a time.
Enable best-effort forwarding for CSI output
port 0.
When this mode is enabled, no attempt is
made to synchronize the video traffic. When
multiple sources have data available to
forward, the data will tend to be forwarded in a
round-robin fashion.
0: Round robin forwarding disabled
1: Round robin forwarding enabled
Only one of CSI0_RR_FWD and
CSI0_SYNC_FWD must be enabled at a time.
Reserved
Forwarding synchronization failed for CSI
output port 1
During Synchronized forwarding, this flag
indicates a failure of synchronized video has
been detected. For this bit to be set, the
forwarding process must have previously been
successful at sending at least one
synchronized video frame.
0: No failure
1: Synchronization failure
This bit is cleared on read.
Forwarding synchronization failed for CSI
output port 0 During Synchronized forwarding,
this flag indicates a failure of synchronized
video has been detected. For this bit to be set,
the forwarding process must have previously
been successful at sending at least one
synchronized video frame.
0: No failure
1: Synchronization failure
This bit is cleared on read.
Forwarding synchronized for CSI output port 1
During Synchronized forwarding, this bit
indicates that the forwarding engine is currently
able to provide synchronized video from
enabled Receive ports. This bit will always be
0 if Synchronized forwarding is disabled.
0: Video is not synchronized
1: Video is synchronized
Forwarding synchronized for CSI output port 0
During Synchronized forwarding, this bit
indicates that the forwarding engine is currently
able to provide synchronized video from
enabled Receive ports. This bit will always be
0 if Synchronized forwarding is disabled.
0: Video is not synchronized
1: Video is synchronized
Global Interrupt Enable:
Enables interrupt on the interrupt signal to the
controller.
