132 SEG / 65 COM DRIVER & CONTROLLER FOR STN LCD
Serial Interface (PS = "L")
When the S6B0724 is active, serial data (DB7) and serial clock (DB6) inputs are enabled. And not active, the internal
8-bit shift register and the 3-bit counter are reset. Serial data can be read on the rising edge of serial clock going into
DB6 and processed as 8-bit parallel data on the eighth serial clock. Serial data input is display data when RS is high
and control data when RS is low. Since the clock signal (DB6) is easy to be affected by the external noise caused by
the line length, the operation check on the actual machine is recommended.
