TNETE211 Register Descriptions

Table B±1. PHY Generic Control Register Bits (Continued)

Bit	Name	Function
11	PDOWN	Power down: When this bit is set (default), the PHY is placed in a low-power consump-
		tion state. This bit resets the 802.12 MAC state machine to MAC0. It stops the Tx and
		Rx functions and disables the oscillator by deasserting POSCEN² . In power-down
		mode, PDOWN is the only bit that can be written to.
10	ISOLATE	Isolate: When this bit is set (default), the PHY electrically isolates its data paths from the
		MII. In this state it does not respond to MTKD[3::0], MTXEN, and MTXER inputs, and
		presents a high impedance on its MTCLK, MRCLK, MRXDV, MRXER, MRXD0±3, and
		MCOL outputs. It will, however, still respond to management frames on MDIO and
		MDCLK.
9	0	Autoconfiguration enable: Not implemented
8	0	Duplex mode: VG currently does not support a full-duplex mode
7	COLTEST	Collision test mode: Setting this bit to 1 causes the PHY to assert the collision sense
		signal MCOL whenever transmit enable (MTXEN) is asserted.
6±0	Reserved	Read as 0

² Oscillator enable from the TNETE211
