Register Set Descriptions
All register access can though the I
2
C multi-byte read and write.
(1) Mode A Register (Address 00h, RO)
This register consist of a model name and revision number. Currently Hyundai has three types of CMOS image
sensor chip, 400*300, 640*480 and 800*600 resolution each. The upper 4 bits is
model_name
[3:0] and the lower
4 bits is
rev_num[3:0].
For example it’s value 12h, this mean 400*300 resolution
and revision2.0 chip.
< model_name > < rev_num
>
400*300 : 0001b Rev. 2.0 : 0010b
(2) Mode B Register (Address 01h, default : 04h, R/W)
This register defines major operation mode of the chip.
n
Mode B[7:6] :
oper_mode
(operating mode) <
default value : 00b>
Define operating modes between normal operation and optical and function test operation.
Test operation mode is used for optical and function test. Except for default value, these bits are
reserved for manufacturer.

Mode B [5:4] :

(data types) <
default value : 00b>
These bits define output pixel data types. For Correlated Double Sampling(CDS), every the pixel of image sensor
are measured twice, reference and data respectively, and reference values or data values can be read out through
pixel data pins selectively using these control bits. To remove the noise caused by circuit, i.e. Fixed Pattern
Noise,
the image sensor performs the CDS in default value. Three output data types are supported as follows.
