Serial Interface (PS = "L")
When the S6B0721 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.

Busy Flag
The Busy Flag indicates whether the S6B0721 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.
