CS8920 Technical Reference Manual
(NDIS 2X, ODI, NDIS 3X, etc.). Default is
DOS (single threaded OS).
Bit 10: Wakeup Capable
Indicates the adapter is capable of
supporting the Automatic Wakeup feature.
Default is not supported.
Bit 9: Wakeup Configured
Indicates the adapter is configured to
support Automatic Wakeup. (Reset block
of EEPROM contains proper information to
support Automatic Wakeup.) Default is
not configured for Automatic Wakeup.
Bit 8: Wakeup Enabled
Indicates the Automatic Wakeup feature is
enabled. Default is disabled.
Bit 7: DC to DC Converter Polarity
Refer to Section 2.2.2.9. (Must be
initialized by OEM before shipping
adapter.)
Bit 6-5: Media Type In Use
Indicates the type of media the driver
should use (10Base-T, AUI, 10Base-2) or if
driver should auto-detect media in use.
Default is auto-detect.
Bit 4: Reserved (set to 0)
Bit 3: Adapter Provides HW Standby
Circuitry
Indicates the presence of hardware standby
circuitry on the adapter. Refer to Section
3.7 of the CS8920 Data Sheet. (Must be
initialized by OEM before shipping
adapter.)
Bit 2: Adapter Provides 10Base-2
Circuitry
Indicates the presence of 10Base-2 circuitry
on the adapter. (Must be initialized by
OEM before shipping adapter.)
Bit 1: Adapter Provides AUI Circuitry
Indicates the presence of AUI circuitry on
the adapter. (Must be initialized by OEM
before shipping adapter.)
Bit 0: Adapter Provides 10Base-T
Circuitry
Indicates the presence of 10Base-T
circuitry on the adapter. (Must be
initialized by OEM before shipping
adapter.)
3.3.8 Manufacturing Date
This word is the adapter’s manufacture date
encoded in 16 bits, YR-MO-DY format.
(Must be initialized by OEM before
shipping adapter.)
Bits 15-9: Two Least-significant Digits of
Year
Seven bits for a range of 00 to 99 decimal.
A roll-over to 00 will be interpreted as the
year 2000.
Bits 8-5: Month
Four bits for a range of 01 to 12.
Bits 4-0 Day
Five bits for a range of 01 to 31.
3.3.9 IEEE Physical Address (copy)
This field is a copy of the three words at
address 1Ch to 1Eh. (Must be initialized
by OEM before shipping adapter.)
