CMOS Image Sensor Pin Definition and Introduction.
1. PowerDown / StandBy
 Set Sensor enter Sleep mode, may shutdown the master clock of sensor, generally active: high. If not use connect to DGND.
2. Reset
 Clean sensor registry and set to default value, generally active: low. (Notes: OV9655 Reset pin active: high.)
3. /OE(Output Enable)
 Control the data[7:0] output, generally active: low. If not use connect to DGND.
4. Line_Valid / HSYNC / HREF
 Horizontal synchronization signal.
5. Frame_Valid / VSYNC
 Vertical synchronization signal.
6. XCLKIN / CLK_IN / MCLK / SYSCLK
 System master clock. Generally Micron sensor is 54MHz, OmniVision sensor 48MHz.
7. PCLK / PIXCLK / VCLK
 Pixel clock.
8. SCLK / SIO-C / SCL
 I2C /SCCB clock.
9. SDATA / SIO-D / SDA
 I2C / SCCB data.
