Select Interface mode with the MPU.
In IM = "Low" : Serial mode,
In IM = "High" : 4-bit/8-bit bus mode.
In bus mode, used as register selection input.
In RS/CS = "High", Data register is selected. In
RS/CS = "Low", Instruction register is selected.
In serial mode, used as chip selection input.
In RS/CS = "Low", selected. When RS/CS =
"High", not selected.(Low access enable)
In bus mode, used as read/write selection input.
In RW/SID = "High", read operation. When
RW/SID = "Low", write operation.
In serial mode, used for data input pin.
In bus mode, used as read_write enable signal.
In serial mode, used as serial clock input pin.
In 8-bit bus mode, used as lowest bi-directional
data bit. During 4-bit bus mode, Open this pin.
In serial mode, used as serial data output pin. If
not in read operation, open this pin.
In 8-bit bus mode, used as low order bi-
directional data bus.
During 4-bit bus mode or serial mode, open
these pins.
In 8-bit bus mode, used as high order bi-
directional data bus. In case of 4-bit bus mode,
used as both high and low order.
DB7 used for Busy Flag output.
During serial mode, open these pins.
