R0 – R4 (Pin 37-Pin 41)

These are key switch scan pulse output pins. During the scan operating, "L" level is output in

sequence. All pluses go to "L" level when scanning stops.

C0 – C5 (Pin 31-Pin 36)

These are input pins that detect the key status. These pins have pull-up resistors. Key matrices

are formed with pins R0 – R4.

INT (Pin 45)

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

completed, and returns to "L" by a load pulse after data output or when the "Scan Stop"

command is written. (The pin is in "L" status during reset.)

If this pin is not used, leave it unconnected.
