4.8 PCI Express

4.8.1 PCI Express x1

There are four one-lane PCI Express ports available in the PCH NM10. The

ports are compliant to the PCI Express 1.0 specification running at 2.5 Gb/s.

Only two PCIe x1 Ports, 0~1, are left on the CT-CCV6X COM™ Express

connector since Port 2 is occupied by GbE and Port 3 is occupied by USB3.0.

4.9 High Definition Audio

The High Definition Audio (HDA) controller is integrated with PCH NM10. 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[2:0]) provided by the PCH support up to three

codecs.
