C bus operation is only selected when SSB pin is left floating. And a valid transmission should be starting
from writing the slave address 7AH, which is mask option, to MTV018. The protocol is shown in Figure 2.

Where S=Slave address, R=Row address, C=Column address, D=Display data
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 different
row address and column address. Format (b) is recommended for updating data that has same row address
but 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 the for-
mat (c) is applied. Furthermore, the undefined locations in display or fonts RAM should be filled with dummy
data.
There are 3 types of data should be accessed through the serial data interface, one is ADDRESS bytes of dis-
play registers, second is ATTRIBUTE bytes of display registers and other is user fonts RAM data, the protocol
are same for all except the bit6 and bit5 of row address. The MSB(b7) is used to distinguish row and column
addresses when transferring data from external controller. The bit6 of row address is used to distinguish dis-
play registers and user fonts RAM data and the bit6 of column address is used to differentiate the column
address for format (a), (b) and format (c) respectively. Bit5 of row address for display register is used to distin-
guish ADDRESS byte when it is set to "0" and ATTRIBUTE byte when it is set to "1". See Table 1.
