Select whether input ports (K00–K03, K10 and
K20–K23) will each be supplemented with pull
down resistors or not. When "GATE DIRECT" is
selected, see to it that entry floating state does not
occur. Select "WITH RESISTOR" pull down
resistor for unused ports.
Moreover, the input port status is changed from
high level (V
DD
resistors, a delay of approximately 1 msec in
waveform rise time will occur depending on the
pull down resistor and entry load time constant.
Because of this, when input reading is to be
conducted, ensure the appropriate wait time with
the program.
The configuration of the pull down resistor circuit
is shown in Figure 3.3.2.

Select the output specification for the output ports
(R00–R03).
Either complementary output or Pch open drain
output may be selected.
When output port is to be used on key matrix
configuration, select Pch open drain output.
For unused output ports, select complementary
output.
The output circuit configuration is shown in Figure
3.3.3.
