Linefeed Shadow.
This register reflects the actual realtime linefeed status. Automatic operations may cause
actual linefeed state transitions regardless of the Linefeed register settings (e.g., when
the Linefeed register is in the ringing state, the Linefeed Shadow register will reflect the
ringing state during ringing bursts and the OHT state during silent periods between ring-
ing bursts).
