• If control signal from MPU is HZ, an over-current may flow through the IC. A protection is required to prevent
the HZ signal at the input pins.

In serial mode, no data can be read from DDRAM.
• When connected to an 8080-series MPU ;
This is active-LOW. This pin is connected to the RD signal of the
8080-series MPU. While this signal is low, SED15B1 series data
bus is an output status.
• When connected to an 6800-series MPU ;
This is active-HIGH. This is used as an enable clock input pin of the
6800-series MPU.
• When connected to an 8080-series MPU ;
This is active-LOW. This pin is connected to the WR signal of the
8080-series MPU. The signals on the data bus are latched at the
rising edge of the WR signal.
•When connected to an 6800-series MPU ;
This is the read/write control signal input .
MPU interface selection pin.
Serial data input/parallel data input selection pin.
The following applies depending on the P/S status :
When P/S=LOW,D5 to D0 are HZ. D5 to D0 may be HIGH, LOW or
Open, and moreover A0, RD, WR, C86 may be HIGH, LOW or
Open.
External clock input. When external clock is halted, CL must be LOW.
If internal clock (on-chip CR oscillation circuit) is selected, CL
connected to V
LCD segment driver output.
LCD common driver output.
LCD common driver output for the indicator. When it is not used,
it is made open.
These are terminals for IC chip testing.
TEST1 to TEST4 are recommended to connect to V
