Description
RSTB
Input Reset input pin. When RSTB is “L”, internal initialization procedure is executed.
These pins select interface operation mode.

Note: Refer to “Interface Selection” for detailed information.
Chip select input pin.
CSB
Input CSB=“L”: This chip is selected and the MPU interface is active.
CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance).
The function of this pin is different in parallel and serial interface.
In parallel interface: A0 is register selection input.
A0
Input
A0 = "H": inputs on data bus are display data;
A0 = "L": inputs on data bus are command.
In serial interface: this pad will be used as SCL (serial-clock) input
Read / Write execution control pin. (This pin is only used in parallel interface)
MPU Type
RWR
Description
RWR
Input
6800-series
Read / Write control input pin
R/W R/W = “H” : read
R/W = “L” : write
8080-series
Write enable clock input pin.
/WR
The data are latched at the rising edge of the /WR signal.
This pin is not used in serial interfaces and should be connected to VDD1.
