Ball Function
Active Low output signal, asserted when AEN is Low and A15-A4 decode to the
KSZ8841M 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 ball needs an
external 4.7K pull-up resistor.
Cycle Not
For VLBus-like mode cycle signal; this ball follows the addressing cycle to signal
the command cycle.
For burst mode (32-bit interface only), this ball stays High for read cycles and
Low for write cycles.
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 ball is pull-up.
EEPROM is disabled when this ball is pull-down or no connect.
Port 1 LED indicator
See the description in balls A10, B10, and C10.
EEPROM Data Out
This ball is connected to DI input of the serial EEPROM.
EEPROM Serial Clock
A 4
on-chip bus speed @ 125 MHz) serial output clock cycle to load configuration
data from the serial EEPROM.
EEPROM Data In
This ball is connected to DO output of the serial EEPROM when EEEN is pull-
up.
This ball can be pull-down for 8-bit bus mode, pull-up for 16-bit bus mode or
don’t care for 32-bit 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.
Write Strobe Not
Asynchronous write strobe, active Low.
Address Strobe Not
For systems that require address latching, the rising edge of ADSN indicates the
latching moment of A15-A1 and AEN.
Full-chip power-down. Low = Power down; High or floating = Normal operation.
