    Interrupt factor flag (K10–K13)
    *1 Initial value at initial reset
    *2 Not set in the circuit
    *3 Constantly "0" when being read
    K00–K03: K0 port input port data (FF21H)
    K10–K13: K1 port input port data (FF25H)
    Input data of the input port terminals can be read with these registers.
    When "1" is read: High level
    When "0" is read: Low level
    Writing: Invalid
    The reading is "1" when the terminal voltage of the eight bits of the input ports (K00–K03, K10–K13) goes
    high (VDD), and "0" when the voltage goes low (VSS).
    These bits are dedicated for reading, so writing cannot be done.
