3 Pin-SPI Interface (PS0 = "L" , PS1 = "L")
To write data to the DDRAM, send Data Direction Command in 3-Pin SPI mode. Data is latched at the rising edge
of SCLK. And the DDRAM column address pointer will be increased by one automatically.

Set No. of Data Bytes(DDL)
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:
l
In spite of transmission of data, if CS1B will be disable, state terminates abnormally. Next state is
initialized.

Busy Flag
The Busy Flag indicates whether the KS0759 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.
