Pin Function
Interrupt
Active Low signal to host CPU to indicate an interrupt status bit is set, this pin need
an external 4.7K pull-up resistor.
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.
Read Strobe Not
Asynchronous read strobe, active Low.
EEPROM Chip Select
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.
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.
Port 2 LED indicator
See the description in pins 6, 7, and 8.
Digital IO ground
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).
VLBus-like Mode
Pull-down or float: Bus interface is configured for synchronous mode.
Pull-up: Bus interface is configured for 8-bit or 16-bit asynchronous mode or EISA-
like burst mode.
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.
Port 1 LED indicator. See the description in pins 3, 4, and 5.
EEPROM Data Out
This pin is connected to DI input of the serial EEPROM.
EEPROM Serial Clock
A 4
EEPROM Data In
This pin is connected to DO output of the serial EEPROM when EEEN is pull-up.
This pin can be pull-down for 8-bit bus mode, pull-up for 16-bus mode or don’t care
for 32-bus mode when EEEN is pull-down (without EEPROM).
Synchronous Write/Read
Write/Read signal for synchronous bus accesses. Write cycles when high and Read
cycles when low.
Address Enable
Address qualifier for the address decoding, active Low.
μ
s serial output clock to load configuration data from the serial EEPROM.
