Read / Write execution control pin
They connect to the standard 8-bit MPU bus via the 8 bit bi-directional bus.When
the following interface is selected and the XCS pin is high, the following pins
become highimpedance, which should be fixed to VDD or VSS.
In IIC Interface
D7: SCL; D6: SI ; D0, D1: SA1, SA0
D3, D2: Acknowledgement
D4, D5, D8 should be fixed to VDD or VSS.

Write enable clock input pin
The data on DB0 to DB8 are latched at the
rising edge of the /WR signal.
Description
Read / Write control input pin
-RW = “H”: When E is “H”, DB0 to DB8 are
in an output status.
-RW = “L”: The data on DB0 to DB8 are
latched at the falling edge of the E signal.
Read enable clock input pin
When /RD is “L”, DB0 to DB8 are in an
output status.
