FrameSync Low Time bits 15:8
The value programmed to the FS_HIGH_TIME
register should be reduced by 1 from the
desired delay. For example, a value of 0 in the
FRAMESYNC_HIGH_TIME field will result in a
1 cycle high pulse on the FrameSync signal.
FrameSync Low Time bits 7:0
The value programmed to the FS_HIGH_TIME
register should be reduced by 1 from the
desired delay. For example, a value of 0 in the
FRAMESYNC_HIGH_TIME field will result in a
1 cycle high pulse on the FrameSync signal.
CSI-2 Maximum Frame Count bits 15:8
In RAW mode operation, the FPD3 Receiver
will create CSI-2 video frames. For the Frame
Start and Frame End packets of each video
frame, a 16-bit frame number field is
generated. If the Maximum Frame Count value
is set to 0, the frame number is disabled and
will always be 0. If Maximum Frame Count
value is non-zero, the frame number will
increment for each from 1 up to the Maximum
Frame Count value before resetting to 1.
