Networking Silicon — Alert on LAN* ASIC
4.13
Register Bh; Software Status Byte 2
The Software Byte 2 register is used to provide detailed software information to the packet
recipient. This byte provides a method of sending specific information from the software and is
transmitted with each packet. It is intended to be valid when the Software Event bit is set in the
Event Status register.
4.14
Register Ch; EEPROM Access
The EEPROM register is used to give EEPROM status and allow access to the individual EEPROM
pins. EEPROM read complete status and invalid checksum status are indicated in this register. A
GPIO bit interface is provided to allow software to access and write directly to the EEPROM.
4.15
Register Dh; Test Mode
The Test Mode register is used to access internal test modes of the Alert on LAN ASIC and to force
a software reset of the ASIC.

EE_COMP
RO
EEPROM Read Complete Indication.
This bit is set to
1b after the configuration EEPROM read is complete.

EEPROM Invalid Checksum Indication.
This bit
should only be read after the EEPROM read has been
completed.
1 = Invalid checksum detected

EE_SK
R/W
EESK Output State.
This bit sets EE_SK status.
0b
a. The default value of EE_ICKSM is 1b after reset. After valid data has been detected, EE_ICKSM is set to 0b, valid checksum
detected.

TST_RST
R/W
SC
Alert on LAN Software Reset.
This bit is used to reset
the Alert on LAN. It performs the equivalent of a
hardware reset and re-reads the EEPROM. This bit
self-clears and the reset completes after four clock
cycles.

TST_MODE
R/W
Test Mode.
The Test Mode enable bit provides access
into the Alert on LAN ASIC’s Vector Test Mode
coverage.
