VMDS-10242 VSC8658 Datasheet Revision 4.1

Note Transmitter Test mode (bits 15:13) operates in the manner described in IEEE standard 802.3,

section 40.6.1.1.2. When using any of the Transmitter Test modes, the Auto-Media Sense functionality

must be disabled. For more information, see Extended PHY Control Set 1, page 37.
