In serial mode, no data can be read from DDRAM.
8-bit bi-directional data bus to be connected to the standard 8-bit or
16-bit MPU data bus.
When the serial interface is selected (P/S=LOW) ;
At this time, D0 through D5 will go under the Hz mode.
When the chip selects are in non-active state, D0 through D7 will
go under the Hz mode.
Control/data flag input.
Chip select input. Data input is enable when CS is low.
When RES is caused to go low, initialization is executed.
A reset operation is performed at the signal level.
• When connected to an 8080-series MPU ;
• When connected to an 6800-series MPU ;
• When connected to an 8080-series MPU ;
• When connected to an 6800-series MPU ;
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 or LOW.
This is active-LOW. This pin is connected to the RD signal of the
8080-series MPU. While this signal is low, S1D15A06 series data
bus in an output status.
This is active-HIGH. This is used as an enable clock input pin of
the 6800-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.
This is the read/write control signal input .
A0=HIGH : The data on D7 to D0 is display data.
A0=LOW : The data on D7 to D0 is control data.
HIGH
LOW
R/W=HIGH : Read.
R/W=LOW : Write.
C86=HIGH : 6800-series MPU interface
C86=LOW : 8080-series MPU interface
P/S=HIGH : Parallel data input
P/S=LOW : Serial data input
