Bit 0 is used to reset the digital logic of the sensor while

preserving the existing two−wire serial interface

configuration. Furthermore, by asserting the soft reset, the

sensor aborts the current frame it is processing and starts

a new frame. Bit 1 is a shadowed reset control register bit to

explicitly reset the automatic gain and exposure control

feature.

These two bits are self−resetting bits and also return to “0”

during two−wire serial inter−face reads.

STANDBY Control

The sensor goes into standby mode by setting STANDBY

to HIGH. Once the sensor detects that STANDBY is

asserted, it completes the current frame before disabling the

digital logic, internal clocks, and analog power enable

signal. To release the sensor out from the standby mode,

reset STANDBY back to LOW. The LVDS must be powered

to ensure that the device is in standby mode. See ”Appendix

A: Power−On Reset and Standby Timing” for more

information on standby.

Monitor Mode Control

Monitor mode is controlled by:

• R0xD9 Monitor Mode Enable

• R0xC0 Monitor Mode Image Capture Control

The sensor goes into monitor mode when R0xD9[0] is set

to HIGH. In this mode, the sensor first captures

a programmable number of frames (R0xC0), then goes into

a sleep period for five minutes. The cycle of sleeping for five

minutes and waking up to capture a number of frames

continues until R0xD9[0] is cleared to return to normal

operation.

In some applications when monitor mode is enabled, the

purpose of capturing frames is to calibrate the gain and

exposure of the scene using automatic gain and exposure

control feature. This feature typically takes less than 10

frames to settle. In case a larger number of frames is needed,

the value of R0xC0 may be increased to capture more

frames.

During the sleep period, none of the analog circuitry and

a very small fraction of digital logic (including

a five−minute timer) is powered. The master clock

(SYSCLK) is therefore always required.

READ MODE OPTIONS

(Also see “Output Data Format” and “Output Data

Timing”.)

Column Flip

By setting bit 5 of R0x0D or R0x0E the readout order of

the columns is reversed, as shown in Figure 30.

Row Flip

By setting bit 4 of R0x0D or R0x0E the readout order of

the rows is reversed, as shown in Figure 31.

Pixel Binning

In addition to windowing mode in which smaller

resolutions (CIF, QCIF) are obtained by selecting a smaller

window from the sensor array, the MT9V024 also provides

the ability to down−sample the entire image captured by the

pixel array using pixel binning.
