3 Pin-SPI Interface (PS = "L", C68 = "L")
In 3-Pin SPI Interface mode, the pre-defined instruction called Display Data Length, is used to indicate whether
serial data input is display or instruction data instead of RS pin. The data is handled as instruction data until the
Display Data Length instruction is issued. This Display Data Length instruction consists of two bytes instruction. The
first byte instruction enables the next instruction to be valid, and the data of the second byte indicates that a
specified number of display data bytes (1 to 256) are to be transmitted. The next byte after the display data string is
handled as instruction data. For details, refers to figure 4.

Figure 4. 3 Pin SPI Timing (RS is not used)
This command is used in 3-Pin SPI mode only. It will be two continuous commands, the first byte controls the data
direction and informs the LCD driver the second byte will be number of data bytes will be write. After these two
commands sending out, the following messages will be data. If data is stopped in transmitting, it is not valid data.
New data will be transferred serially with most significant bit first.
*NOTES:
- In spite of transmission of data, if CS1B will be disable, state terminates abnormally. Next state is initialized.
- The number of writing display data = DDL register value + 1
Busy Flag
The busy flag indicates whether the S6B1400X is operating or not. When DB7 is “H” in read status operation, this
device is in busy status and will accept only read status instruction. If the cycle time is correct, the microprocessor
needs not to check this flag before each instruction, which improves the MPU performance.
