• Manufacturer Part Number: MTV038
• Description: On-screen Display Controller For Crt/lcd Monitor
• Manufacturer: ETC-unknow

There are three transmission formats shown as below:
Format (a) R - C - D -> R - C - D -> R - C - D .....
Format (b) R - C - D -> C - D -> C - D -> C - D .....
Format (c) R - C - D -> D -> D -> D -> D -> D .....
Where R=Row address, C=Column address, D=Display data

from writing the slave address 7AH(write mode), or 7BH(read mode) to MTV038. The protocol is shown in
Figure 2. And the auto sizing video measurement data (total 12 bytes) are read only registers and the others
are write only registers.
There are three transmission formats for I
Format (a) S - R - C - D -> R - C - D -> R - C - D .....
Format (b) S - R - C - D -> C - D -> C - D -> C - D .....
Format (c) S - R - C - D -> D -> D -> D -> D -> D .....
Where S=Slave address, R=Row address, C=Column address, D=Display data
And there is one transmission formats for I
Format (a) S -> D -> D -> D -> D -> D -> D -> D -> D -> D -> D -> D -> D -> D -> D -> dummy D .....
Where S=Slave address, D=Measurement data
In the I
byte 9 and continues with dummy data until stop condition occurred when R/W bit is set to 1.
Each arbitrary length of data packet consists of 3 portions viz, Row address (R), Column address (C), and
Display data (D). Format (a) is suitable for updating small amount of data which will be allocated with a differ-
ent row address and column address. Format (b) is recommended for updating data that has the same row
address but a different column address. Massive data updating or full screen data change should use format
(c) to increase transmission efficiency. The row and column address will be incremented automatically when
