IS_AN_TX_EN

Autonegotiation Transmit Enable Status. Autonegotiation transmit enable. This bit indicates that the

autonegotiation is active and controlling the transmitter, and arbitration has not yet reached autonegotiation

good check state or the autonegotiation good state. That is, the link_control signals have not been set to

enable.

0x1

IS_CFG_MST

Leader Status. If link_control = enable (for example, B10L_LINK_CTRL_EN = 1), this indicates whether the

PHY is operating as leader (and not follower).

0x0

IS_CFG_SLV

Follower Status. If link_control = enable (for example, B10L_LINK_CTRL_EN = 1), this indicates whether the

PHY is operating as follower (and not leader).

0x0

IS_TX_LVL_HI

Transmit Level High Status. Indicates that the PHY is operating with high transmit levels (2.4 V), and not low

transmit levels (1.0 V).

0x0

IS_TX_LVL_LO

Transmit Level Low Status. Indicates that the PHY is operating with low transmit levels (1.0 V), and not low

transmit levels (2.4 V).
