25.3.23 Register 22 (16h) – Control & Status Register
22.15 – Disable Link-Integrity State Machine
When bit 22.15 is set to “0”, the VSC8211 link integrity state machine runs automatically. When bit 22.15 is set to “1”, the link
integrity state machine is bypassed, and the PHY is forced into link pass status.
22.14 – Disable Jabber Detect
When bit 22.14 is set to “0”, the VSC8211 automatically shuts off the transmitter when a transmission request exceeds the
IEEE-specified time limit. When bit 22.14 is set to “1”, transmission requests are allowed to be arbitrarily long without shutting
down the transmitter.
22.13 – Disable 10BASE-T Echo Mode
When this bit is set, TXEN and TXD will not be echoed on the RXDV abd RXD pins respectively in 10BASE-T half duplex mode.
22.12 – SQE Disable Mode
When bit 22.12 is set to “1”, SQE (Signal Quality Error) pulses are not sent. Note that this control bit applies in 10BASE-T HDX
mode only.
