• Description: 34com/80seg Driver & Controller For Dot Matrix Lcd
• Manufacturer: Newhaven Display International, Inc

If 3-Pin SPI mode is used, CSB (DB5), SID (DB7), and SCLK (DB6) are used. they
are chip selection, serial input data, and serial clock input, relatively. 3-Pin SPI
mode does not use RS for data/instruction selection. Data length instruction should
be used to realize data/instruction and data length instruction also indicates length
of data. The example of timing sequence is shown below; data length instruction is
followed by data set.
Note: Following is the master SPI clock mode of MPU.
For serial interface data, bus lines (DB5 to DB7) are used. 3 – Pin SPI
Example of timing sequence
Intel 8051 interface (Serial)
Idle state for clock is a high level，data is clocked into RW1067 on the rising edge of SCLK.
