D15 to D0
I/O
They connect to the standard 8-bit or 16-bit MPU bus via the
8/16-bit bi-directional bus.
When the following interface is selected and the CS pin is high, the
following pins become high impedance.
1
8-bit parallel: D15-D18 are in the state of high impedance
2
Serial interface: D15-D0 are in the state of high impedance
This pin is used to input serial data when the serial interface is selected
.
This pin is used to input serial clock when the serial interface is selected.
The data is converted in the rising edge.
These pins are used to select either of the MPU interfaces.
Depending on status of IF1, IF2 and IF3, following selection is made.

Normally, the least significant bit of the MPU
s address bus is
connected to identify a parameter or display data from a command.
HIGH: Indicates that data entered to D15 to D0 or SI is a
parameter or display data.
LOW: Indicates that data entered to D15 to D0 or SI is a command.
This function is disabled when the 9-bit serial interface is selected.
This pin is used to enter chip select signal. It is activated when
CS = LOW, enabling interface with MPU.
It goes active LOW when connected to the 80 series MPU.
This pin is used to connect RD signal from the 80 series MPU. The data
bus is maintained in the output status as long as this signal is LOW.
It goes active HIGH when connected to the 68 series MPU.
In this case, this pin is used to enter the enable clock from 68 series MPU.
It goes active LOW when connected to the 80 series MPU.
This pin connects WR signal from the 80 series MPU. Signal on
the data bus is latched at the positive going edge of WR signal.
This pin enters the read/write signal when connected to the 68 series MPU.
R/W = HIGH: Read
R/W = LOW: Write
Causing RES to LOW performs initialization.
Reset operation is performed according the level of RES signal.
