I2C Registers

5.2.4

Video timing registers

Indexes in the range [0x52 - 0x62] control the line and frame length of the sensor. The registers are

as follows:

q line length

q frame length

The line length is specified in a number of pixel clocks, whereas the frame length is specified in a

number of lines.The range of some parameter values is limited and any value programmed out of

the range is clipped as follows:

q Values greater than the maximum are clipped to the maximum allowed.

q Values less than the default for a given mode are clipped to the default value.
