KI1 to KI5
1 to 5
Key scan inputs. These pins have built-in pull-down resistors.
H
I
GND
Key scan outputs. Although normal key scan timing lines require diodes to be
KS1 to KS3
6 to 8
inserted in the timing lines to prevent shorts, since these outputs are unbalanced

CMOS transistor outputs, these outputs will not be damaged by shorting when
these outputs are used to from a key matrix.
Key scan outputs and general-purpose output ports shared-function pins.
KS4/P4 to KS6/P2
9 to 11
These pins can be set the key scan output ports or the general-purpose output

resistor and capacitor at this pin.
Reset input. that re-initializes the LSI internal states. This pin must be used.
When RES is low (VSS)
— Key scanning disabled: KS1 to KS3 = low (VSS).
— Key scan outputs and general output ports shared-function pins:
KS4/P4 to KS6/P2 = low (VSS).
RES
16
— General-purpose output port: P1 = low (VSS).
L
I
GND
— All the key data is reset to low.
When RES is high (VDD)
— The states of the pins as key scan output pins or general-purpose output
ports, must be set with the control data.
— And key scanning is a enabled.
Note that serial data must be transferred when RES is high.
CE
18
Serial data interface. Connections to the controller. Note that DO, being
