Extending line lengths
The user can extend the line length by writing to serial registers 82 and 83. The line length padding
is inserted after the EAV sequence, ensuring that the distance between the SAV and EAV
sequences remains constant.
3.1.7 Frame format
Each video frame is composed of a sequence of data lines as illustrated in Figure 11.

Extending the inter-frame period
The user may choose to extend the inter-frame period by increasing the frame length by writing to
serial registers 97 and 98. In this event, the appropriate number of additional blank lines is inserted
between the End Of Frame (EOF) line and the Start Of Frame (SOF) line. This means that the
distance between SOF and EOF remains constant.
