VV5430
6.
The pixels in the VV5430 sensor array can be output to AVO as alternate columns and rows by setting bits 5 and 6 in the Setup
Code_1 register (header code 0001 - see Serial Interface for details). This has the effect of generating two, or four, identical low
resolution images in one field:
When this facility is combined with AVO Enable selected for the appropriate quarter, it is possible to display the images from four
separate cameras on one monitor.
In order to achieve four identical images in one frame (from one sensor), bits 5 and 6 of Setup Code_1 must both be set via the
serial interface, that is HSHUFFLE=1 and VSHUFFLE=1. The former interleaves odd and even pixel lines in the image, and the
latter interleaves pixel columns. OE[0..2] can then Enable AVO output for any one quarter of the display field.

The VV5430 video output can be Enabled in different parts of the standard field by programming bits 9..11 of Setup Code_2, that
is CE[0..2]; when not enabled, the AVO output is Tristated, that is floating at high impedance. Thus, a number of different sensor
AVO outputs can be connected together and selectively enabled. This feature, together with bus addressing of up to four
VV5430s on one serial link, is intended for multi-sensor systems that, in conjunction with bits 5,6 of Setup Code_1, enable the
images from up to four cameras to be displayed on a single monitor.
By programming CE[0..2] different areas of the field can be enabled:.
