The value of Vci is converted twice. To use
the three times converter, the same
capacitance as that of C1-C2 should be
connected here.
The value of Vci is converted three times.
Select Interface mode with the MPU.
When IM = “Low”: Serial mode,
When IM = “High”: 4-bit/8-bit bus mode.
In bus mode, used as register selection
input. When RS/CS = “High”, Data register is
selected. When RS/CS
register is selected.
In serial mode, used as chip selection input.
When RS/CS = “Low”, selected.
When RS/CS = “High”, not selected
(Low access enable).
In bus mode, used as read/write selection
input.
When 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
bidirectional 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
bidirectional data bus.
During 4-bit bus mode or serial mode, open
these pins.
In 8-bit bus mode, used as high order
bidirectional data bus. In 4-bit bus mode,
used as both high and low order.
DB7 used for Busy Flag output.
During serial mode, open these pins.
