High-Performance 16-bit Non-PCI 10/100 Ethernet Controller with Variable Voltage I/O
Fixed definition of bits 11:10 when equal to “11” by
adding “advertise support for..” to beginning of
definition. Also added note stating “When both
symmetric PAUSE and asymmetric PAUSE
support are advertised, the device will only be
configured to, at most, one of the two settings
upon auto-negotiation completion.”
Added note: “When wake-up frame detection is
enabled via the WUEN bit of the
up Control and Status
up frame will wake-up the device despite the state
of the Disable Broadcast Frame (BCAST) bit in the
MAC_CR—MAC Control
Fixed typo in bit 9: “... Mac Address [1:0] bit set to
0.” was changed to “...Mac Address [0] bit set to 0.”
“checksum = [B0, B1] + C0 + [B2, B3] + C1 + …
+ [0, BN] + CN-1” changed to “checksum = [B1,
B0] + C0 + [B3, B2] + C1 + … + [0, BN] + CN-1”
Added section. Added references to this section
throughout the pin description tables as applicable.
Removed the system memory block and arrow
above the microprocessor/ microcontroller
Pin assignment information re-organized into
separate table.
Note added to EECLK pin description to indicate
proper usage.
CORRECTION
