    Type
    Pin Function
    Active Low signal to host CPU to indicate an interrupt status bit is set, this pin need an
    external 4.7K pull-up resistor.
    17
    LDEVN
    Opd
    Local Device Not
    Active Low output signal, asserted when AEN is Low and A15-A4 decode to the
    KSZ8862M address programmed into the high byte of the base address register. LDEVN
    is a combinational decode of the Address and AEN signal.
    18
    RDN
    Ipd
    Read Strobe Not
    Asynchronous read strobe, active Low.

    ARDY
    Opd
    Asynchronous Ready
    ARDY may be used when interfacing asynchronous buses to extend bus access cycles.
    It is asynchronous to the host CPU or bus clock. This pin needs an external 4.7K pull-up
    resistor.
    21
    CYCLEN
    Ipd
    Cycle Not
    For VLBus-like mode cycle signal; this pin follows the addressing cycle to signal the
    command cycle.
    For burst mode (32-bit interface only), this pin stays High for read cycles and Low for
    write cycles.
    22
    P2LED3
    Opd
    Port 2 LED indicator. See the description in pins 6, 7, and 8.

    VDDCO
    P
    1.2V digital core voltage output (internal 1.2V LDO power supply output), this 1.2V output
    pin provides power to VDDC, VDDA and VDDAP pins.
    Note: Internally generated power voltage. Do not connect an external power supply to this
    pin. This pin is used for connecting external filter (Ferrite Bead and capacitors).
    25
    VLBUSN
    Ipd
    VLBus-like Mode
    Pull-down or float: Bus interface is configured for synchronous mode.
    Pull-up: Bus interface is configured for 32-bit asynchronous mode or EISA-like burst
    mode.
    26
    EEEN
    Ipd
    EEPROM Enable
    EEPROM is enabled and connected when this pin is pull-up.
    EEPROM is disabled when this pin is pull-down or no connect.
    27
    P1LED3
    Opd
    Port 1 LED indicator
    See the description in pins 3, 4, and 5.

    EEPROM Serial Clock
    A 4
    s serial output clock to load configuration data from the serial EEPROM.
    30
    EEDI
    Ipd
    EEPROM Data In
    This pin is connected to DO output of the serial EEPROM when EEEN is pull-up.
    This pin can be pulled-down for 8-bit bus mode, pulled-up for 16-bus mode or either way
    for 32-bus mode when EEEN is pulled-down (without EEPROM).
    31
    SWR
    Ipd
    Synchronous Write/Read
    Write/Read signal for synchronous bus accesses. Write cycles when high and Read
    cycles when low.
    32
    AEN
    Ipu
    Address Enable
    Address qualifier for the address decoding, active Low.
    33
    WRN
    Ipd
    Write Strobe Not Asynchronous write strobe, active Low.
