RW_WR
I
RW_WR pin is only used in parallel interface.
MPU type
RW_WR
Description
6800-series
RW
Read / Write control input pin
Write status: RW = “L”.
Read status: RW = “H”.
8080-series
/WR
Write enable clock input pin
The data on D0 to D15 are latched at the rising
edge of the /WR signal.
When in the serial interface, connect it to VDDI.
E_RD
I
E_RD pin is only used in parallel interface.
MPU Type
E_RD
Description
6800-series
E
Enable clock pin:
Write status: The data on D0 to D15 are latched at
the falling edge of the E signal.
Read status: The data on D0 to D15 are latched at
the rising edge of the E signal.
8080-series
/RD
Read enable clock input pin
The data on D0 to D15 are latched at the falling
edge of the /WR signal.
When in the serial interface, connect it to VDDI.
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.
In 8-bit parallel: D15-D8 pins are in the state of high impedance should connect to VDDI.
2.
In 3-line/4-line interface D0 pad will be used for SI function
3.
In 4-line interface D1 pad will be used for A0 function
4.
In Serial interface: unused pins are in the state of high impedance should connect to VDDI.
SI
I
SI is used to input serial data when the serial interface is selected.(3 line and 4 line)
It is used by “D0” pad, See Table 7.2-1.
SCL
I
SCL is used to input serial clock when the serial interface is selected.
The data is converted in the rising edge. (3 line and 4 line)
It is used by “A0” pad , See Table 7.2-1.
TE
O
Tearing effect output.
