Level-Triggered Sticky Bit

This type of status bit is set whenever the condition that it represents is asserted. The

bit remains set until the condition is no longer true and the status bit is cleared by writ-

ing a zero.

MLD

Multicast Listening Discovery

MLT-3

Multi-Level Transmission Encoding (3-Levels). A tri-level encoding method where a

change in the logic level represents a code bit “1” and the logic output remaining at the

same level represents a code bit “0”.
