82543GC Gigabit Ethernet Controller Specification Update

segmentation. The Transfer DMA Control Register (TXDMAC) will be removed from the developer’s manual

and text in 12.6 Reset should change.

Note: Erratum #14 prohibits using TCP segmentation regardless of the preemption function.

Affected Docs: OR-2710 82543GC Gigabit Ethernet Controller Developer’s Manual Rev. 2.01.

10. Remove Gigabit Half-Duplex Transmit Burst Timer Control Function (TBT)

Problem: The controller does not have the capability to control transmit burst length for Gigabit half-duplex operation

through register programming. The Transmit Burst Timer Register (TBT) will be removed from the developer’s

manual.

Note: Erratum #12 prohibits Gigabit half-duplex mode operation.

Affected Docs: OR-2710 82543GC Gigabit Ethernet Controller Developer’s Manual Rev. 2.01.

11. Remove Adaptive IFS Throttle Function (AIT)

Problem: The controller does not have the ability to increase inter-packet gap (beyond TIPG control) during back-to-back

transmit operation and Gigabit half-duplex operation. The Adaptive IFS Throttle Register (AIT) will be removed

from the developer’s manual. Affected sections of the developer’s manual include 9.2.2.2 Packet Bursting, 9.4.1

Adaptive IFS and 9.4.2 Burst Mode IFS.

Note: Erratum #12 prohibits Gigabit half-duplex mode operation.

Affected Docs: OR-2710 82543GC Gigabit Ethernet Controller Developer’s Manual Rev. 2.01.
