The MT9P031 pixel array consists of a 2752-column by 2004-row matrix of pixels
addressed by column and row. The address (column 0, row 0) represents the upper-right
corner of the entire array, looking at the sensor, as shown in Figure 4 on page 9.
The array consists of a 2592-column by 1944-row active region in the center representing
the default output image, surrounded by a boundary region (also active), surrounded by
a border of dark pixels (see Table 4 and Table 5). The boundary region can be used to
avoid edge effects when doing color processing to achieve a 2592 x 1944 result image,
while the optically black column and rows can be used to monitor the black level.
Description
When LOW, the MT9P031 asynchronously resets. When driven HIGH, it resumes normal
operation with all configuration registers set to factory defaults.

normal operation resumes.
Standby. When LOW, the chip enters a low-power standby mode. It resumes normal
operation when the pin is driven HIGH.
Snapshot trigger. Used to trigger one frame of output in snapshot modes, and to indicate the
end of exposure in bulb exposure modes.
Serial address. When HIGH, the MT9P031 responds to device ID (BA)

Frame valid. Driven HIGH during active pixels and horizontal blanking of each frame and
LOW during vertical blanking.
Line valid. Driven HIGH with active pixels of each line and LOW during blanking periods.
Snapshot strobe. Driven HIGH when all pixels are exposing in snapshot modes.
