(DEVELOPMENT SOFTWARE TOOL FOR S1C60N08)
Select the output specification when the I/O ports
(P00–P03 and P10–P13) are in output mode.
Either complementary output or Pch open drain
output may be selected.
The circuit configuration of the output driver is the
same as those of the output ports R00–R03 (Figure
3.3.3).
Select complementary output for unused ports.
The I/O ports can control the input/output direction
according to the IOC bit (2EEH•D0 and
2FEH•D0); at "1" and "0" settings, it is set to
output port and input port, respectively.
The pull down resistor of this port is turned on by
the read signal and is normally turned off to
minimize leak current.
Because of this, when the port is set for input, take
care that a floating state does not occur in the
terminal.
The I/O port circuit configuration is shown in
Figure 3.3.7.

PLEASE SELECT NO.(1) ? 1
SIN PULL DOWN RESISTOR 1. WITH RESISTOR SELECTED
Select whether pull down resistor will be supple-
mented to the SIN terminal (SIO data input
terminal). When "GATE DIRECT" is selected, take
care that input floating state does not occur. Select
"WITH RESISTOR" if the SIN terminal will not be
used.
