• R0 - R4

These are keyswitch scan signal output pins. During the scan operation, "L" level is output in

the order of R0, R1, …, R4. All signals go to "L" level when scanning stops. (See keyscan)

• C0 - C4

These are input pins that detect the key status. Pull-up resistor is included. Key matrices are

formed with R0 -␣ R4 pins.

• INT

This is the keyscan end signal output pin. This pin goes to "H" level when one scan cycle ends,

and returns to "L" level by a load signal after data is output or after the "Keyscan Stop" command

is entered. (This pin also returns to "L" level at reset.)
