The High Definition Audio (HDA) controller is integrated with PCH QM77. It
communicates with the external codec(s) over the Intel® High Definition Audio
serial link. The controller consists of a set of DMA engines that are used to
move samples of digitally encoded data between system memory and an
external codec(s). The PCH implements a single Serial Data Output signal
(HDA_SDOUT) that is connected to all external codecs. Three Serial Digital
Input signals (HDA_SDIN[0:02] provided by the PCH support up to three
codecs.

4.10 Ethernet
The QM77 integrates a Gigabit Ethernet (GbE) controller. The controller with
Intel® 82579LM LAN PHY provides 10/100/1000Mb/s interface. The Intel®
82579 is connected to Port 7 of the PCIe x1 in the PCH. Gigabit transformer
has to be designed on the Carrier Board.
