Reset input
S6A0094 is initialized while RESETB is low.
Chip selection input
S6A0094 is selected while CSB is low.
Register selection input
When RS = "Low", instruction register
When RS = "High", data register
In 80-series MPU interface mode
This pin is connected to WR pin of MPU and is an active low write signal.
In 68-series MPU interface mode
This pin is connected to R/W pin of MPU.
When RW_WR = "Low", write mode
When RW_WR = "High", read mode
In 80-series MPU interface mode
This pin is connected to RD pin of MPU and is a active low read signal.
In 68-series MPU interface mode
This pin is connected to E pin of MPU and enable read or write command
according to RW_WR signal.
When 8-bit bus mode, used as bi-directional data bus DB0 - DB7.
During 4-bit bus mode, only DB4 - DB7 are used. In this case DB0 - DB3 pins
are not used.
When serial mode, DB6 (SCL) is used as serial clock input pin and DB7 (SI)
is used as serial data input pin.
