indicates that dock is electrically connected and that software may detect and
enumerate the docked codecs. For the undocking process, it indicates that the
dock is electrically isolated and that software may report to the user that physical
undocking may commence. This bit gets set to a 1 by hardware when the DM bit
transitions from 0-to-1 (docking) or from 1-to-0 (undocking). Note that this bit is
set regardless of the state of the DMIE bit.
writing a 0 to the Dock Attach (GCTL.DA) bit is completed (DOCK_EN#
deasserted). This bit indicates to software that the docked codec(s) may be
physically undocked.
writing a 1 to the Dock Attach (GCTL.DA) bit is completed (AZ_DOCK_RST#
