ASF_CNTL—ASF Control Register
(LAN Controller—B1:D8:F0)
Offset Address: E2h
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.
