Data Type
: Eight-bit word.
USAGE : For test purposes, the sensor will read out the contents of the pixel array, one pixel per frame. To start a pixel
grab, write anything to this register to reset the pointer to pixel 0,0. Then read the PIXRDY bit in the Motion register.
When the PIXRDY bit is set, there is valid data in this register to read out. After the data in this register is read, the
pointer will automatically increment to the next pixel. Reading may continue indefinitely; once a complete frame’s
worth of pixels has been read, PIXFIRST will be set to high to indicate the start of the first pixel and the address pointer
will start at the beginning location again.
