TNETE211 Register Descriptions

Table B±3. ThunderLAN PHY Control Register Bits

Bit	Name	Function
15	IGLINK	Ignore link: When this bit is set to 0, the 100VG-AnyLAN Demand Priority PHY expects
		to receive link pulses from the hub, and sets the LINK bit in the GEN_sts register to
		0 if they are not present. When this bit is set to 1, link pulses are ignored and the LINK
		bit is always set to 1.
14	MCRS	MCRS output value: The MCRS pin of the PMI is deasserted when the transmit/
		receive medium is idle. Once the transmit/receive medium is nonidle, the pin is as-
		serted.
13	PTLSWEN	PMD TLS write control value: The PTLSWEN pin of the PMI is used to control the PMD
		TLS write control. It should be set to 0 for all normal operations.
12	PRLSREN	PMD RLS read control value: The PRLSREN pin of the PMI is used to control the PMD
		RLS read control. It should be set to 0 for all normal operations.
11±6	Reserved	Read as 0s
5	TRFAIL	Training fail indicator: Writing a 1 to this bit causes the PMI to restart training when the
		next window is reached. This bit forces the PMI to interrupt the driver with a retrain
		event when retraining occurs.
4	TRIDLE	Training idle request: Writing a 1 to this bit causes the PMI to indicate training idle to
		the PMD whenever there is no transmit request pending. Writing a 0 to this bit causes
		the PMI to send idle up whenever there is no transmit request pending.
3	NPMDW	Not physical media dependant wrap: This bit only has meaning when the LOOPBK bit
		of the GEN_ctl is a 1. Writing a 1 to this bit causes the PMI to wrap the Tx data to the
		Rx data at the far side of the PMI. Writing a 0 to this bit causes the PMI to wrap the
		Tx data to the Rx data in the analog device attached to the PMI.
2	NFEW	Not far end wrap: This bit only has meaning when the LOOPBK bit of the GEN_ctl is
		a 1. Writing a 1 to this bit causes the PMI to wrap the Tx data to the Rx data at the MII
		interface. Writing a 0 to this bit causes the PMI to wrap the Tx data to the Rx data based
		on the value of the NPMDW bit.
1	INTEN	Interrupt enable: Writing a 1 to this bit causes the PMI to generate interrupts to the MII
		if any one of the event conditions occur. Writing a 0 to this bit causes the PMI to not
		generate an MII interrupt even though an event condition has occurred.
0	TINT	Test interrupt: Writing a 1 to this bit causes the PMI to generate an interrupt to the MII.
		Writing a 0 to this bit causes the PMI to not generate an MII interrupt. This bit is used
		to test the interrupts from the PHY prior to requiring them.
