12 / 29 page SINGLE IC CMOS COLOR AND B/W DIGITAL CAMERAS March 4, 2000 Version 1.0 12 Executing a software power down through the I 2C interface suspends internal circuit activity, but does not halt the device clock. The current requirements drop to less than 1mA in this mode. 1.2.11 Configure OV6630/OV6130 Two methods are provided to configure OV6630/OV6130 for specific application requirements. At power up, OV6630/OV6130 reads the status of certain pins to determine what, if any, power up pin programming default settings are requested. Once the reading of the external pins status is completed, the device configures its internal registers according to the specified pins. Not all device functions are available for configuration through external pins. Power up pin programming occurs in 1024 system clock cycles. A more flexible and comprehensive method to configure OV6630/OV6130 is to use its on-chip I 2C register programming capability. The I 2C interface provides access to all of the device’s programmable internal registers. See I2C Bus Protocol Format for further details about using the I 2C interface on the OV6630/OV6130 camera device. CLK HSYNC VSYNC 1 Line=472 T CLK 1 Frame=625 x 472 T CLK T CLK T HS T VS Notes: T HS > 6 TCLK (2), THS < TVS < 472 TCLK HSYNC period is (472 T CLK) VSYNC period is (625 x 472 T CLK) OV6630/OV6130 will be stable after 1 field (2nd VSYNC) Figure 6.
