Pixel Data3
Access: Read/Write
Data Type: Two status bits, six bit pixel data.
USAGE: Digital Pixel data. Minimum value = 0, maximum value = 63. Any writes to this register resets the pixel hardware
Shutter_Upper3
Access: Read
Shutter_Lower3
Access: Read
Data Type: Sixteen bit word.
USAGE: Units are clock cycles; default value is 0x0100HEX. Read Shutter_Upper first, then Shutter_Lower. They should

so that the next read from the Pixel Data register will read pixel #1 and the StartOfFrame bit will be set. Subse-
quent reads will auto increment the pixel number.
To dump a complete image, set the LED to forced awake mode, write anything to this register, then read 361
times where the DataValid bit is set. On the 362th read, the StartOfFrame bit will be set indicating that we have
completed one frame of pixels and are starting back at pixel 1.
It takes at least 361 frames to complete an image as we can only read 1 pixel per frame.
The pixel hardware is armed with any read or write to the Pixel Data register and will output pixel data from the
next available frame. So, if you were to write the Pixel Data register, wait 5 seconds then read the Pixel Data
register; the reported pixel data is from 5 seconds ago.
be read consecutively. The shutter is adjusted to keep the average and maximum pixel values within normal
operating ranges. The shutter value can be adjusted to a new value on every frame. When the shutter adjusts,
it changes by ± 1/16 of the current value. Shown in Figure 32 is a graph of 250 sequentially acquired shutter
values, while the sensor was moved slowly over white paper.
