• R0 - R4

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

in the order of R0, R1, …, R4. All signals go to "L" level when scanning stops.

• C0 - C5

These are input pins that detect the key status. A pull-up resistor is built in. Key matrices are

formed with R0 -␣ R4 pins.

• INT

This is the keyscan end signal output pin. This pin becomes "H" level when one scan cycle

ends, and returns to "L" level by a load signal after data is output or the "Key Scan Stop"

command is written. (This pin goes to "L" level at reset.)
