AR0130: 1/3-Inch CMOS Digital Image Sensor

Features

Embedded Data

The embedded data contains the configuration of the image being displayed. This

includes all register settings used to capture the current frame. The registers embedded

in these rows are as follows:

Line 1: Registers R0x3000 to R0x312F

Line 2: Registers R0x3136 to R0x31BF, R0x31D0 to R0x31FF

Note:

All undefined registers will have a value of 0.

In parallel mode, since the pixel word depth is 12-bits/pixel, the sensor 16-bit register

data will be transferred over 2 pixels where the register data will be broken up into 8 MSB

and 8 LSB. The alignment of the 8-bit data will be on the 8 MSB bits of the 12-bit pixel

word. For example, of a register value of 0x1234 is to be transmitted, it will be trans-

mitted over 2, 12-bit pixels as follows: 0x120, 0x340.

The first pixel of each line in the embedded data is a tag value of 0x0A0. This signifies

that all subsequent data is 8 bit data aligned to the MSB of the 12-bit pixel.

The figure below summarizes how the embedded data transmission looks like. It should

be noted that data, as shown in Figure 18, is aligned to the MSB of each word:

Format of Embedded Data Output within a Frame

The data embedded in these rows are as follows:

•0x0A0 - identifier

• 0xAA0

• Register Address MSB of the first register

•0xA50

• Register Address LSB of the first register

•0x5A0

• Register Value MSB of the first register addressed

•0x5A0

• Register Value LSB of the first register addressed

•0x5A0

• Register Value MSB of the register at first address + 2

•0x5A0

• Register Value LSB of the register at first address + 2

•0x5A0

•etc.
