HB7121B
CMOS IMAGE SENSOR
With 8-bit ADC
(1) Mode A Register (Address 00h, RO)
This register consist of a model name and revision number. 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 >
400*300 : 0001b
< rev_num >
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.
