I2C BUS CONTROLLED 3CH VIDEO PRE-AMP WITH OSD CONTROLLER FOR HIGH RESOLUTION COLOR DISPLAY

MONITOR

OSD part data input (Sequence)

(a) Sub addresses are consists of 16 bits.

(b) Data is consists of 16 bits.

(c) Sub addresses and data are communicated in 8-bit units. Input the

lower 8 bits before the upper 8 bits. Make input from the MSB

side.

(d) After the start state has been attained and the control byte

(7CH) received, the next 16 bits (2bytes) are for inputting the

address. Addresses are increased in increments for every 16

bits (2 bytes) of data input thereafter. As a result, it is not

necessary to input the address from the second data.
