RW_WR
In 8080-series MPU interface mode, this pin is connected to WR pin of MPU and is an
active high write signal.
I
In 6800-series MPU interface mode, this pin is connected to R/W pin of MPU.
When RW_WR = "High", read mode
When RW_WR = "Low", write mode
E_RD
In 8080-series MPU interface mode, this pin is connected to RD pin of MPU and is a low
