*NOTE: When PS is "L", DB0 to DB5 are high impedance and E_RD and RW_WR
must be fixed to either "H" or "L".
Microprocessor interface select input pin
PS0 = “H” , PS1 = "H": 6800-series parallel MPU interface
PS0 = “H” , PS1 = "L": 8080-series parallel MPU interface
PS0 = “L” , PS1 = "H": 4 Pin-SPI serial MPU interface
PS0 = “L” , PS1 = "L": 3 Pin-SPI serial MPU interface
Chip select input pins
Data/instruction I/O is enabled only when CS1B is "L" . When chip select is non-active,
DB0 to DB7 may be high impedance.
Register select input pin
RS = "H": DB0 to DB7 are display data
RS = "L": DB0 to DB7 are control data
Read / Write execution control pin
PS1
MPU Type
RW_WR
Read/Write control input pin
RW = "H": read
RW = "L": write
Write enable clock input pin
The data on DB0 to DB7 are latched at the rising
edge of the /WR signal.
