ASF_CNTL—ASF Control Register
(LAN Controller—B1:D8:F0)
Offset Address:
Default Value:
This register contains enables for special modes and SOS events. CTL_PWRLS should be set if
ASF should be expecting a power loss due to software action. Otherwise, an EEPROM reload will
happen when the power is lost.

SMBus Hang SOS Enable (CTL_SMBHG) — R/W.
0 = Disable
1 = Enables SMBus Hang SOS to be sent.
Watchdog SOS Enable (CTL_WDG) — R/W.
0 = Disable.
1 = Enables Watchdog SOS to be sent.
Link Loss SOS Enable (CTL_LINK) — R/W.
0 = Disable.
1 = Enables Link Loss SOS to be sent.
OS Hung Status (CTL_OSHUNG) — RO.
1 = This bit will be set to 1 when ASF has detected a Watchdog Expiration.
NOTE: This condition is only clearable by a PCI RST# assertion (system reset).
Power-Up SOS Enable (CTL_PWRUP) — R/W.
0 = Disable.
1 = Enables Power-Up SOS to be sent.
Reserved
Receive ARP Enable (CTL_RXARP) — R/W. The LAN controller interface provides a mode where
all packets can be requested.
0 = Disable.
1 = Enable. ASF requests all packets when doing a Receive Enable. This is necessary in LAN
NOTE: Changes to this bit will not take effect until the next Receive Enable command to the LAN.
Power Loss OK (CTL_PWRLS) — R/W.
0 = Power Loss will reload EEPROM
1 = Power Loss will not reload EEPROM
