Updated Pass Control Frames (bit 2) description to
“When set, the MAC will pass the pause frame to
the host...”
nLED1 description modified to indicate that the
signal is driven low when operating speed is
100Mbs and is driven high during autonegotiation,
when the cable is disconnected, and during 10
Mbs operation.
RX Data FIFO port is aliased to 16 WORD
locations, not 16 DWORD locations.
TX Data FIFO port is aliased to 16 WORD
locations, not 16 DWORD locations.
Added note stating TX Checksum calculation
should not be used for UDP packets under IPv6.
Added pin 1 designator to pin diagram
Added note: “Do not drive input signals without
power supplied to the device.”
Added power sequence timing section
Fixed various typos

Added power consumption values.
Updated with current consumption values for
various VDDVARIO values.
Added input capacitance and input leakage values.
Changed incorrect “GPT_CNT” reference to
“GPT_LOAD”: “On a reset, or when the
TIMER_EN bit changes from set ‘1’ to cleared ‘0,’
the GPT_LOAD field is initialized to FFFFh.”
Corrected MAC Address Loaded (bit 8) type from
“RO” to “R/WC”
Updated crystal specifications:
Drive Level: 300uW
ESR: 50 Ohms.
